Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42200, here are decompositions:

  • 3 + 42197 = 42200
  • 7 + 42193 = 42200
  • 13 + 42187 = 42200
  • 19 + 42181 = 42200
  • 31 + 42169 = 42200
  • 43 + 42157 = 42200
  • 61 + 42139 = 42200
  • 127 + 42073 = 42200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42200 first appears in π at position 64,013 of the decimal expansion (the 64,013ordinal-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.
