Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42558, here are decompositions:

  • 59 + 42499 = 42558
  • 67 + 42491 = 42558
  • 71 + 42487 = 42558
  • 97 + 42461 = 42558
  • 101 + 42457 = 42558
  • 107 + 42451 = 42558
  • 149 + 42409 = 42558
  • 151 + 42407 = 42558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42558 first appears in π at position 176,508 of the decimal expansion (the 176,508ordinal-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.
