Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40190, here are decompositions:

  • 13 + 40177 = 40190
  • 37 + 40153 = 40190
  • 61 + 40129 = 40190
  • 67 + 40123 = 40190
  • 79 + 40111 = 40190
  • 97 + 40093 = 40190
  • 103 + 40087 = 40190
  • 127 + 40063 = 40190

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40190 first appears in π at position 9,843 of the decimal expansion (the 9,843ordinal-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.
