Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556398, here are decompositions:

  • 47 + 556351 = 556398
  • 67 + 556331 = 556398
  • 71 + 556327 = 556398
  • 109 + 556289 = 556398
  • 127 + 556271 = 556398
  • 131 + 556267 = 556398
  • 137 + 556261 = 556398
  • 179 + 556219 = 556398

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 556,398 and was likely granted around 1895.

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

Position in π

The digit sequence 556398 first appears in π at position 238,941 of the decimal expansion (the 238,941ordinal-suffix:st 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.
