Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19140, here are decompositions:

  • 19 + 19121 = 19140
  • 53 + 19087 = 19140
  • 59 + 19081 = 19140
  • 61 + 19079 = 19140
  • 67 + 19073 = 19140
  • 71 + 19069 = 19140
  • 89 + 19051 = 19140
  • 103 + 19037 = 19140

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19140 first appears in π at position 202,549 of the decimal expansion (the 202,549ordinal-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.
