Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42562, here are decompositions:

  • 5 + 42557 = 42562
  • 29 + 42533 = 42562
  • 53 + 42509 = 42562
  • 71 + 42491 = 42562
  • 89 + 42473 = 42562
  • 101 + 42461 = 42562
  • 239 + 42323 = 42562
  • 263 + 42299 = 42562

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42562 first appears in π at position 7,024 of the decimal expansion (the 7,024ordinal-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.
