Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524600, here are decompositions:

  • 13 + 31524587 = 31524600
  • 31 + 31524569 = 31524600
  • 59 + 31524541 = 31524600
  • 67 + 31524533 = 31524600
  • 83 + 31524517 = 31524600
  • 101 + 31524499 = 31524600
  • 131 + 31524469 = 31524600
  • 181 + 31524419 = 31524600

Showing the first eight; more decompositions exist.
