Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42588, here are decompositions:

  • 11 + 42577 = 42588
  • 17 + 42571 = 42588
  • 19 + 42569 = 42588
  • 31 + 42557 = 42588
  • 79 + 42509 = 42588
  • 89 + 42499 = 42588
  • 97 + 42491 = 42588
  • 101 + 42487 = 42588

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42588 first appears in π at position 52,442 of the decimal expansion (the 52,442ordinal-suffix:nd 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.
