Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138496, here are decompositions:

  • 3 + 138493 = 138496
  • 47 + 138449 = 138496
  • 89 + 138407 = 138496
  • 107 + 138389 = 138496
  • 173 + 138323 = 138496
  • 257 + 138239 = 138496
  • 317 + 138179 = 138496
  • 353 + 138143 = 138496

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 138,496 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 138496 first appears in π at position 134,094 of the decimal expansion (the 134,094ordinal-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.
