Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489526, here are decompositions:

  • 7 + 31489519 = 31489526
  • 37 + 31489489 = 31489526
  • 109 + 31489417 = 31489526
  • 127 + 31489399 = 31489526
  • 163 + 31489363 = 31489526
  • 283 + 31489243 = 31489526
  • 349 + 31489177 = 31489526
  • 379 + 31489147 = 31489526

Showing the first eight; more decompositions exist.
