Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589416, here are decompositions:

  • 83 + 31589333 = 31589416
  • 113 + 31589303 = 31589416
  • 233 + 31589183 = 31589416
  • 317 + 31589099 = 31589416
  • 347 + 31589069 = 31589416
  • 359 + 31589057 = 31589416
  • 389 + 31589027 = 31589416
  • 569 + 31588847 = 31589416

Showing the first eight; more decompositions exist.
