Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528904, here are decompositions:

  • 23 + 528881 = 528904
  • 41 + 528863 = 528904
  • 71 + 528833 = 528904
  • 83 + 528821 = 528904
  • 113 + 528791 = 528904
  • 197 + 528707 = 528904
  • 281 + 528623 = 528904
  • 293 + 528611 = 528904

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 528,904 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 528904 first appears in π at position 528,685 of the decimal expansion (the 528,685ordinal-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.
