Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576608, here are decompositions:

  • 29 + 31576579 = 31576608
  • 59 + 31576549 = 31576608
  • 67 + 31576541 = 31576608
  • 79 + 31576529 = 31576608
  • 97 + 31576511 = 31576608
  • 131 + 31576477 = 31576608
  • 149 + 31576459 = 31576608
  • 181 + 31576427 = 31576608

Showing the first eight; more decompositions exist.
