Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508928, here are decompositions:

  • 19 + 508909 = 508928
  • 61 + 508867 = 508928
  • 139 + 508789 = 508928
  • 157 + 508771 = 508928
  • 307 + 508621 = 508928
  • 349 + 508579 = 508928
  • 379 + 508549 = 508928
  • 397 + 508531 = 508928

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 508,928 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 508928 first appears in π at position 73,208 of the decimal expansion (the 73,208ordinal-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.
