Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528870, here are decompositions:

  • 17 + 31528853 = 31528870
  • 29 + 31528841 = 31528870
  • 47 + 31528823 = 31528870
  • 59 + 31528811 = 31528870
  • 173 + 31528697 = 31528870
  • 257 + 31528613 = 31528870
  • 311 + 31528559 = 31528870
  • 419 + 31528451 = 31528870

Showing the first eight; more decompositions exist.
