Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981954, here are decompositions:

  • 5 + 981949 = 981954
  • 7 + 981947 = 981954
  • 13 + 981941 = 981954
  • 41 + 981913 = 981954
  • 67 + 981887 = 981954
  • 131 + 981823 = 981954
  • 137 + 981817 = 981954
  • 157 + 981797 = 981954

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 981,954 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 981954 first appears in π at position 409,101 of the decimal expansion (the 409,101ordinal-suffix:st 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.
