Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981792, here are decompositions:

  • 23 + 981769 = 981792
  • 61 + 981731 = 981792
  • 79 + 981713 = 981792
  • 89 + 981703 = 981792
  • 101 + 981691 = 981792
  • 109 + 981683 = 981792
  • 139 + 981653 = 981792
  • 191 + 981601 = 981792

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 981,792 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 981792 first appears in π at position 448,285 of the decimal expansion (the 448,285ordinal-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.
