Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524360, here are decompositions:

  • 17 + 31524343 = 31524360
  • 29 + 31524331 = 31524360
  • 59 + 31524301 = 31524360
  • 67 + 31524293 = 31524360
  • 83 + 31524277 = 31524360
  • 89 + 31524271 = 31524360
  • 103 + 31524257 = 31524360
  • 137 + 31524223 = 31524360

Showing the first eight; more decompositions exist.
