Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613152, here are decompositions:

  • 191 + 31612961 = 31613152
  • 239 + 31612913 = 31613152
  • 419 + 31612733 = 31613152
  • 491 + 31612661 = 31613152
  • 563 + 31612589 = 31613152
  • 569 + 31612583 = 31613152
  • 761 + 31612391 = 31613152
  • 839 + 31612313 = 31613152

Showing the first eight; more decompositions exist.
