Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20366, here are decompositions:

  • 7 + 20359 = 20366
  • 13 + 20353 = 20366
  • 19 + 20347 = 20366
  • 43 + 20323 = 20366
  • 79 + 20287 = 20366
  • 97 + 20269 = 20366
  • 193 + 20173 = 20366
  • 223 + 20143 = 20366

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20366 first appears in π at position 165,086 of the decimal expansion (the 165,086ordinal-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.
