Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528542, here are decompositions:

  • 31 + 528511 = 528542
  • 73 + 528469 = 528542
  • 109 + 528433 = 528542
  • 139 + 528403 = 528542
  • 151 + 528391 = 528542
  • 229 + 528313 = 528542
  • 379 + 528163 = 528542
  • 499 + 528043 = 528542

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 528,542 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 528542 first appears in π at position 787,541 of the decimal expansion (the 787,541ordinal-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.
