Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560106, here are decompositions:

  • 47 + 31560059 = 31560106
  • 59 + 31560047 = 31560106
  • 257 + 31559849 = 31560106
  • 293 + 31559813 = 31560106
  • 419 + 31559687 = 31560106
  • 467 + 31559639 = 31560106
  • 569 + 31559537 = 31560106
  • 659 + 31559447 = 31560106

Showing the first eight; more decompositions exist.
