Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550962, here are decompositions:

  • 41 + 31550921 = 31550962
  • 83 + 31550879 = 31550962
  • 239 + 31550723 = 31550962
  • 251 + 31550711 = 31550962
  • 263 + 31550699 = 31550962
  • 281 + 31550681 = 31550962
  • 389 + 31550573 = 31550962
  • 419 + 31550543 = 31550962

Showing the first eight; more decompositions exist.
