Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42758, here are decompositions:

  • 7 + 42751 = 42758
  • 31 + 42727 = 42758
  • 61 + 42697 = 42758
  • 109 + 42649 = 42758
  • 181 + 42577 = 42758
  • 271 + 42487 = 42758
  • 307 + 42451 = 42758
  • 349 + 42409 = 42758

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42758 first appears in π at position 191,585 of the decimal expansion (the 191,585ordinal-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.
