Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603916, here are decompositions:

  • 37 + 31603879 = 31603916
  • 73 + 31603843 = 31603916
  • 199 + 31603717 = 31603916
  • 307 + 31603609 = 31603916
  • 349 + 31603567 = 31603916
  • 397 + 31603519 = 31603916
  • 523 + 31603393 = 31603916
  • 607 + 31603309 = 31603916

Showing the first eight; more decompositions exist.
