Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550824, here are decompositions:

  • 17 + 31550807 = 31550824
  • 23 + 31550801 = 31550824
  • 101 + 31550723 = 31550824
  • 113 + 31550711 = 31550824
  • 197 + 31550627 = 31550824
  • 251 + 31550573 = 31550824
  • 281 + 31550543 = 31550824
  • 293 + 31550531 = 31550824

Showing the first eight; more decompositions exist.
