Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508400, here are decompositions:

  • 7 + 508393 = 508400
  • 37 + 508363 = 508400
  • 73 + 508327 = 508400
  • 103 + 508297 = 508400
  • 127 + 508273 = 508400
  • 157 + 508243 = 508400
  • 163 + 508237 = 508400
  • 229 + 508171 = 508400

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 508,400 and was likely granted around 1893.

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

Position in π

The digit sequence 508400 first appears in π at position 553,085 of the decimal expansion (the 553,085ordinal-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.
