Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500514, here are decompositions:

  • 5 + 31500509 = 31500514
  • 11 + 31500503 = 31500514
  • 107 + 31500407 = 31500514
  • 131 + 31500383 = 31500514
  • 137 + 31500377 = 31500514
  • 233 + 31500281 = 31500514
  • 251 + 31500263 = 31500514
  • 293 + 31500221 = 31500514

Showing the first eight; more decompositions exist.
