Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528880, here are decompositions:

  • 3 + 528877 = 528880
  • 17 + 528863 = 528880
  • 47 + 528833 = 528880
  • 59 + 528821 = 528880
  • 89 + 528791 = 528880
  • 101 + 528779 = 528880
  • 173 + 528707 = 528880
  • 251 + 528629 = 528880

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 528,880 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 528880 first appears in π at position 173,086 of the decimal expansion (the 173,086ordinal-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.
