Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538418, here are decompositions:

  • 7 + 538411 = 538418
  • 19 + 538399 = 538418
  • 61 + 538357 = 538418
  • 109 + 538309 = 538418
  • 151 + 538267 = 538418
  • 271 + 538147 = 538418
  • 367 + 538051 = 538418
  • 499 + 537919 = 538418

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 538,418 and was likely granted around 1894.

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

Position in π

The digit sequence 538418 first appears in π at position 50,365 of the decimal expansion (the 50,365ordinal-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.
