Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42470, here are decompositions:

  • 3 + 42467 = 42470
  • 7 + 42463 = 42470
  • 13 + 42457 = 42470
  • 19 + 42451 = 42470
  • 37 + 42433 = 42470
  • 61 + 42409 = 42470
  • 67 + 42403 = 42470
  • 73 + 42397 = 42470

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42470 first appears in π at position 9,483 of the decimal expansion (the 9,483ordinal-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.
