Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528772, here are decompositions:

  • 53 + 528719 = 528772
  • 113 + 528659 = 528772
  • 149 + 528623 = 528772
  • 263 + 528509 = 528772
  • 281 + 528491 = 528772
  • 353 + 528419 = 528772
  • 359 + 528413 = 528772
  • 389 + 528383 = 528772

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 528,772 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 528772 first appears in π at position 820,931 of the decimal expansion (the 820,931ordinal-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.
