Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104138, here are decompositions:

  • 19 + 104119 = 104138
  • 31 + 104107 = 104138
  • 79 + 104059 = 104138
  • 157 + 103981 = 104138
  • 271 + 103867 = 104138
  • 337 + 103801 = 104138
  • 439 + 103699 = 104138
  • 457 + 103681 = 104138

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 104,138 and was likely granted around 1870.

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

Position in π

The digit sequence 104138 first appears in π at position 423,287 of the decimal expansion (the 423,287ordinal-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.
