Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550834, here are decompositions:

  • 31 + 31550803 = 31550834
  • 37 + 31550797 = 31550834
  • 43 + 31550791 = 31550834
  • 103 + 31550731 = 31550834
  • 163 + 31550671 = 31550834
  • 223 + 31550611 = 31550834
  • 241 + 31550593 = 31550834
  • 277 + 31550557 = 31550834

Showing the first eight; more decompositions exist.
