Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90280, here are decompositions:

  • 17 + 90263 = 90280
  • 41 + 90239 = 90280
  • 53 + 90227 = 90280
  • 83 + 90197 = 90280
  • 89 + 90191 = 90280
  • 107 + 90173 = 90280
  • 131 + 90149 = 90280
  • 173 + 90107 = 90280

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 90280 first appears in π at position 51,990 of the decimal expansion (the 51,990ordinal-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.
