Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42150, here are decompositions:

  • 11 + 42139 = 42150
  • 19 + 42131 = 42150
  • 61 + 42089 = 42150
  • 67 + 42083 = 42150
  • 79 + 42071 = 42150
  • 89 + 42061 = 42150
  • 107 + 42043 = 42150
  • 127 + 42023 = 42150

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42150 first appears in π at position 3,097 of the decimal expansion (the 3,097ordinal-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.
