Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971812, here are decompositions:

  • 29 + 971783 = 971812
  • 53 + 971759 = 971812
  • 59 + 971753 = 971812
  • 89 + 971723 = 971812
  • 113 + 971699 = 971812
  • 173 + 971639 = 971812
  • 251 + 971561 = 971812
  • 263 + 971549 = 971812

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 971,812 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 971812 first appears in π at position 649,672 of the decimal expansion (the 649,672ordinal-suffix:nd 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.
