Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528212, here are decompositions:

  • 199 + 528013 = 528212
  • 211 + 528001 = 528212
  • 229 + 527983 = 528212
  • 271 + 527941 = 528212
  • 283 + 527929 = 528212
  • 331 + 527881 = 528212
  • 409 + 527803 = 528212
  • 463 + 527749 = 528212

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 528,212 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 528212 first appears in π at position 105,533 of the decimal expansion (the 105,533ordinal-suffix:rd 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.
