Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978144, here are decompositions:

  • 31 + 978113 = 978144
  • 53 + 978091 = 978144
  • 67 + 978077 = 978144
  • 71 + 978073 = 978144
  • 73 + 978071 = 978144
  • 103 + 978041 = 978144
  • 107 + 978037 = 978144
  • 113 + 978031 = 978144

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 978,144 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 978144 first appears in π at position 871,735 of the decimal expansion (the 871,735ordinal-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.
