Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499576, here are decompositions:

  • 79 + 31499497 = 31499576
  • 109 + 31499467 = 31499576
  • 193 + 31499383 = 31499576
  • 337 + 31499239 = 31499576
  • 349 + 31499227 = 31499576
  • 439 + 31499137 = 31499576
  • 499 + 31499077 = 31499576
  • 613 + 31498963 = 31499576

Showing the first eight; more decompositions exist.
