Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128134, here are decompositions:

  • 23 + 128111 = 128134
  • 101 + 128033 = 128134
  • 113 + 128021 = 128134
  • 137 + 127997 = 128134
  • 257 + 127877 = 128134
  • 317 + 127817 = 128134
  • 353 + 127781 = 128134
  • 401 + 127733 = 128134

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 128,134 and was likely granted around 1872.

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

Position in π

The digit sequence 128134 first appears in π at position 361,082 of the decimal expansion (the 361,082ordinal-suffix:nd 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.
