Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978000, here are decompositions:

  • 29 + 977971 = 978000
  • 73 + 977927 = 978000
  • 103 + 977897 = 978000
  • 139 + 977861 = 978000
  • 151 + 977849 = 978000
  • 181 + 977819 = 978000
  • 197 + 977803 = 978000
  • 239 + 977761 = 978000

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 978,000 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 978000 first appears in π at position 443,863 of the decimal expansion (the 443,863ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
