Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627864, here are decompositions:

  • 3 + 31627861 = 31627864
  • 53 + 31627811 = 31627864
  • 71 + 31627793 = 31627864
  • 101 + 31627763 = 31627864
  • 113 + 31627751 = 31627864
  • 137 + 31627727 = 31627864
  • 263 + 31627601 = 31627864
  • 353 + 31627511 = 31627864

Showing the first eight; more decompositions exist.
