Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538074, here are decompositions:

  • 3 + 31538071 = 31538074
  • 11 + 31538063 = 31538074
  • 41 + 31538033 = 31538074
  • 251 + 31537823 = 31538074
  • 353 + 31537721 = 31538074
  • 383 + 31537691 = 31538074
  • 443 + 31537631 = 31538074
  • 593 + 31537481 = 31538074

Showing the first eight; more decompositions exist.
