Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609274, here are decompositions:

  • 7 + 31609267 = 31609274
  • 43 + 31609231 = 31609274
  • 61 + 31609213 = 31609274
  • 157 + 31609117 = 31609274
  • 163 + 31609111 = 31609274
  • 181 + 31609093 = 31609274
  • 241 + 31609033 = 31609274
  • 337 + 31608937 = 31609274

Showing the first eight; more decompositions exist.
