Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529972, here are decompositions:

  • 3 + 31529969 = 31529972
  • 73 + 31529899 = 31529972
  • 223 + 31529749 = 31529972
  • 349 + 31529623 = 31529972
  • 379 + 31529593 = 31529972
  • 421 + 31529551 = 31529972
  • 433 + 31529539 = 31529972
  • 541 + 31529431 = 31529972

Showing the first eight; more decompositions exist.
