Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978122, here are decompositions:

  • 31 + 978091 = 978122
  • 43 + 978079 = 978122
  • 73 + 978049 = 978122
  • 151 + 977971 = 978122
  • 199 + 977923 = 978122
  • 241 + 977881 = 978122
  • 331 + 977791 = 978122
  • 601 + 977521 = 978122

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 978,122 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 978122 first appears in π at position 90,837 of the decimal expansion (the 90,837ordinal-suffix:th 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.
