Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523464, here are decompositions:

  • 3 + 31523461 = 31523464
  • 23 + 31523441 = 31523464
  • 53 + 31523411 = 31523464
  • 83 + 31523381 = 31523464
  • 197 + 31523267 = 31523464
  • 227 + 31523237 = 31523464
  • 233 + 31523231 = 31523464
  • 257 + 31523207 = 31523464

Showing the first eight; more decompositions exist.
