Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33228, here are decompositions:

  • 5 + 33223 = 33228
  • 17 + 33211 = 33228
  • 29 + 33199 = 33228
  • 37 + 33191 = 33228
  • 47 + 33181 = 33228
  • 67 + 33161 = 33228
  • 79 + 33149 = 33228
  • 109 + 33119 = 33228

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33228 first appears in π at position 88,081 of the decimal expansion (the 88,081ordinal-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.
