Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11420, here are decompositions:

  • 37 + 11383 = 11420
  • 67 + 11353 = 11420
  • 103 + 11317 = 11420
  • 109 + 11311 = 11420
  • 163 + 11257 = 11420
  • 181 + 11239 = 11420
  • 223 + 11197 = 11420
  • 271 + 11149 = 11420

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11420 first appears in π at position 66,201 of the decimal expansion (the 66,201ordinal-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.
