Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42258, here are decompositions:

  • 19 + 42239 = 42258
  • 31 + 42227 = 42258
  • 37 + 42221 = 42258
  • 61 + 42197 = 42258
  • 71 + 42187 = 42258
  • 79 + 42179 = 42258
  • 89 + 42169 = 42258
  • 101 + 42157 = 42258

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42258 first appears in π at position 350,039 of the decimal expansion (the 350,039ordinal-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.
