Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522128, here are decompositions:

  • 67 + 522061 = 522128
  • 199 + 521929 = 522128
  • 241 + 521887 = 522128
  • 337 + 521791 = 522128
  • 379 + 521749 = 522128
  • 421 + 521707 = 522128
  • 457 + 521671 = 522128
  • 487 + 521641 = 522128

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 522,128 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 522128 first appears in π at position 660,644 of the decimal expansion (the 660,644ordinal-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.
