Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542064, here are decompositions:

  • 41 + 31542023 = 31542064
  • 53 + 31542011 = 31542064
  • 83 + 31541981 = 31542064
  • 131 + 31541933 = 31542064
  • 173 + 31541891 = 31542064
  • 431 + 31541633 = 31542064
  • 467 + 31541597 = 31542064
  • 557 + 31541507 = 31542064

Showing the first eight; more decompositions exist.
