Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569016, here are decompositions:

  • 47 + 31568969 = 31569016
  • 107 + 31568909 = 31569016
  • 137 + 31568879 = 31569016
  • 173 + 31568843 = 31569016
  • 293 + 31568723 = 31569016
  • 359 + 31568657 = 31569016
  • 593 + 31568423 = 31569016
  • 599 + 31568417 = 31569016

Showing the first eight; more decompositions exist.
