Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612552, here are decompositions:

  • 5 + 31612547 = 31612552
  • 71 + 31612481 = 31612552
  • 239 + 31612313 = 31612552
  • 311 + 31612241 = 31612552
  • 353 + 31612199 = 31612552
  • 401 + 31612151 = 31612552
  • 431 + 31612121 = 31612552
  • 443 + 31612109 = 31612552

Showing the first eight; more decompositions exist.
