Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490552, here are decompositions:

  • 43 + 31490509 = 31490552
  • 73 + 31490479 = 31490552
  • 193 + 31490359 = 31490552
  • 229 + 31490323 = 31490552
  • 271 + 31490281 = 31490552
  • 421 + 31490131 = 31490552
  • 433 + 31490119 = 31490552
  • 463 + 31490089 = 31490552

Showing the first eight; more decompositions exist.
