Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627846, here are decompositions:

  • 53 + 31627793 = 31627846
  • 83 + 31627763 = 31627846
  • 197 + 31627649 = 31627846
  • 269 + 31627577 = 31627846
  • 557 + 31627289 = 31627846
  • 599 + 31627247 = 31627846
  • 773 + 31627073 = 31627846
  • 839 + 31627007 = 31627846

Showing the first eight; more decompositions exist.
