Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524350, here are decompositions:

  • 7 + 31524343 = 31524350
  • 19 + 31524331 = 31524350
  • 73 + 31524277 = 31524350
  • 79 + 31524271 = 31524350
  • 127 + 31524223 = 31524350
  • 157 + 31524193 = 31524350
  • 307 + 31524043 = 31524350
  • 337 + 31524013 = 31524350

Showing the first eight; more decompositions exist.
