Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493416, here are decompositions:

  • 167 + 31493249 = 31493416
  • 263 + 31493153 = 31493416
  • 347 + 31493069 = 31493416
  • 359 + 31493057 = 31493416
  • 419 + 31492997 = 31493416
  • 509 + 31492907 = 31493416
  • 557 + 31492859 = 31493416
  • 569 + 31492847 = 31493416

Showing the first eight; more decompositions exist.
