Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997760, here are decompositions:

  • 19 + 997741 = 997760
  • 61 + 997699 = 997760
  • 67 + 997693 = 997760
  • 79 + 997681 = 997760
  • 97 + 997663 = 997760
  • 109 + 997651 = 997760
  • 151 + 997609 = 997760
  • 163 + 997597 = 997760

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 997,760 and was likely granted around 1911.

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

Position in π

The digit sequence 997760 first appears in π at position 765,360 of the decimal expansion (the 765,360ordinal-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.
