Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538506, here are decompositions:

  • 19 + 538487 = 538506
  • 83 + 538423 = 538506
  • 107 + 538399 = 538506
  • 109 + 538397 = 538506
  • 139 + 538367 = 538506
  • 149 + 538357 = 538506
  • 173 + 538333 = 538506
  • 197 + 538309 = 538506

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 538,506 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 538506 first appears in π at position 156,234 of the decimal expansion (the 156,234ordinal-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.
