Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564702, here are decompositions:

  • 41 + 31564661 = 31564702
  • 53 + 31564649 = 31564702
  • 89 + 31564613 = 31564702
  • 263 + 31564439 = 31564702
  • 269 + 31564433 = 31564702
  • 311 + 31564391 = 31564702
  • 431 + 31564271 = 31564702
  • 461 + 31564241 = 31564702

Showing the first eight; more decompositions exist.
