Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620274, here are decompositions:

  • 5 + 31620269 = 31620274
  • 11 + 31620263 = 31620274
  • 71 + 31620203 = 31620274
  • 83 + 31620191 = 31620274
  • 107 + 31620167 = 31620274
  • 167 + 31620107 = 31620274
  • 281 + 31619993 = 31620274
  • 293 + 31619981 = 31620274

Showing the first eight; more decompositions exist.
