Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530178, here are decompositions:

  • 5 + 31530173 = 31530178
  • 149 + 31530029 = 31530178
  • 359 + 31529819 = 31530178
  • 461 + 31529717 = 31530178
  • 509 + 31529669 = 31530178
  • 857 + 31529321 = 31530178
  • 929 + 31529249 = 31530178
  • 1091 + 31529087 = 31530178

Showing the first eight; more decompositions exist.
