Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609214, here are decompositions:

  • 97 + 31609117 = 31609214
  • 103 + 31609111 = 31609214
  • 127 + 31609087 = 31609214
  • 181 + 31609033 = 31609214
  • 277 + 31608937 = 31609214
  • 331 + 31608883 = 31609214
  • 397 + 31608817 = 31609214
  • 421 + 31608793 = 31609214

Showing the first eight; more decompositions exist.
