Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 107978, here are decompositions:

  • 7 + 107971 = 107978
  • 37 + 107941 = 107978
  • 97 + 107881 = 107978
  • 139 + 107839 = 107978
  • 151 + 107827 = 107978
  • 307 + 107671 = 107978
  • 331 + 107647 = 107978
  • 337 + 107641 = 107978

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 107,978 and was likely granted around 1870.

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

Position in π

The digit sequence 107978 first appears in π at position 72,339 of the decimal expansion (the 72,339ordinal-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.
