Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138484, here are decompositions:

  • 23 + 138461 = 138484
  • 83 + 138401 = 138484
  • 113 + 138371 = 138484
  • 173 + 138311 = 138484
  • 233 + 138251 = 138484
  • 293 + 138191 = 138484
  • 383 + 138101 = 138484
  • 431 + 138053 = 138484

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 138,484 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 138484 first appears in π at position 224,217 of the decimal expansion (the 224,217ordinal-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.
