Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594090, here are decompositions:

  • 29 + 31594061 = 31594090
  • 41 + 31594049 = 31594090
  • 107 + 31593983 = 31594090
  • 131 + 31593959 = 31594090
  • 137 + 31593953 = 31594090
  • 251 + 31593839 = 31594090
  • 257 + 31593833 = 31594090
  • 293 + 31593797 = 31594090

Showing the first eight; more decompositions exist.
