Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528738, here are decompositions:

  • 19 + 528719 = 528738
  • 29 + 528709 = 528738
  • 31 + 528707 = 528738
  • 47 + 528691 = 528738
  • 59 + 528679 = 528738
  • 71 + 528667 = 528738
  • 79 + 528659 = 528738
  • 107 + 528631 = 528738

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 528,738 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 528738 first appears in π at position 162,607 of the decimal expansion (the 162,607ordinal-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.
