Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42528, here are decompositions:

  • 19 + 42509 = 42528
  • 29 + 42499 = 42528
  • 37 + 42491 = 42528
  • 41 + 42487 = 42528
  • 61 + 42467 = 42528
  • 67 + 42461 = 42528
  • 71 + 42457 = 42528
  • 131 + 42397 = 42528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42528 first appears in π at position 259,626 of the decimal expansion (the 259,626ordinal-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.
