Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20272, here are decompositions:

  • 3 + 20269 = 20272
  • 11 + 20261 = 20272
  • 23 + 20249 = 20272
  • 41 + 20231 = 20272
  • 53 + 20219 = 20272
  • 71 + 20201 = 20272
  • 89 + 20183 = 20272
  • 149 + 20123 = 20272

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20272 first appears in π at position 102,180 of the decimal expansion (the 102,180ordinal-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.
