Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497194, here are decompositions:

  • 7 + 31497187 = 31497194
  • 37 + 31497157 = 31497194
  • 61 + 31497133 = 31497194
  • 67 + 31497127 = 31497194
  • 193 + 31497001 = 31497194
  • 277 + 31496917 = 31497194
  • 331 + 31496863 = 31497194
  • 367 + 31496827 = 31497194

Showing the first eight; more decompositions exist.
