Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536672, here are decompositions:

  • 43 + 31536629 = 31536672
  • 59 + 31536613 = 31536672
  • 151 + 31536521 = 31536672
  • 173 + 31536499 = 31536672
  • 191 + 31536481 = 31536672
  • 269 + 31536403 = 31536672
  • 281 + 31536391 = 31536672
  • 311 + 31536361 = 31536672

Showing the first eight; more decompositions exist.
