Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148938, here are decompositions:

  • 5 + 148933 = 148938
  • 7 + 148931 = 148938
  • 11 + 148927 = 148938
  • 17 + 148921 = 148938
  • 47 + 148891 = 148938
  • 71 + 148867 = 148938
  • 79 + 148859 = 148938
  • 109 + 148829 = 148938

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 148,938 and was likely granted around 1873.

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

Position in π

The digit sequence 148938 first appears in π at position 271,167 of the decimal expansion (the 271,167ordinal-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.
