Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528392, here are decompositions:

  • 19 + 528373 = 528392
  • 79 + 528313 = 528392
  • 103 + 528289 = 528392
  • 229 + 528163 = 528392
  • 349 + 528043 = 528392
  • 379 + 528013 = 528392
  • 409 + 527983 = 528392
  • 463 + 527929 = 528392

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 528,392 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 528392 first appears in π at position 946,095 of the decimal expansion (the 946,095ordinal-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.
