Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42270, here are decompositions:

  • 13 + 42257 = 42270
  • 31 + 42239 = 42270
  • 43 + 42227 = 42270
  • 47 + 42223 = 42270
  • 61 + 42209 = 42270
  • 73 + 42197 = 42270
  • 83 + 42187 = 42270
  • 89 + 42181 = 42270

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42270 first appears in π at position 125,678 of the decimal expansion (the 125,678ordinal-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.
