Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981948, here are decompositions:

  • 7 + 981941 = 981948
  • 29 + 981919 = 981948
  • 59 + 981889 = 981948
  • 61 + 981887 = 981948
  • 131 + 981817 = 981948
  • 137 + 981811 = 981948
  • 139 + 981809 = 981948
  • 151 + 981797 = 981948

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 981,948 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 981948 first appears in π at position 540,624 of the decimal expansion (the 540,624ordinal-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.
