Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42124, here are decompositions:

  • 23 + 42101 = 42124
  • 41 + 42083 = 42124
  • 53 + 42071 = 42124
  • 101 + 42023 = 42124
  • 107 + 42017 = 42124
  • 167 + 41957 = 42124
  • 197 + 41927 = 42124
  • 227 + 41897 = 42124

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42124 first appears in π at position 33,053 of the decimal expansion (the 33,053ordinal-suffix:rd 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.
