Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20136, here are decompositions:

  • 7 + 20129 = 20136
  • 13 + 20123 = 20136
  • 19 + 20117 = 20136
  • 23 + 20113 = 20136
  • 29 + 20107 = 20136
  • 47 + 20089 = 20136
  • 73 + 20063 = 20136
  • 89 + 20047 = 20136

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20136 first appears in π at position 434,251 of the decimal expansion (the 434,251ordinal-suffix:st 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.
