Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528490, here are decompositions:

  • 3 + 528487 = 528490
  • 71 + 528419 = 528490
  • 89 + 528401 = 528490
  • 107 + 528383 = 528490
  • 173 + 528317 = 528490
  • 191 + 528299 = 528490
  • 227 + 528263 = 528490
  • 293 + 528197 = 528490

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 528,490 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 528490 first appears in π at position 131,608 of the decimal expansion (the 131,608ordinal-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.
