Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42586, here are decompositions:

  • 17 + 42569 = 42586
  • 29 + 42557 = 42586
  • 53 + 42533 = 42586
  • 113 + 42473 = 42586
  • 149 + 42437 = 42586
  • 179 + 42407 = 42586
  • 227 + 42359 = 42586
  • 263 + 42323 = 42586

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42586 first appears in π at position 298,044 of the decimal expansion (the 298,044ordinal-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.
