Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531058, here are decompositions:

  • 79 + 31530979 = 31531058
  • 157 + 31530901 = 31531058
  • 379 + 31530679 = 31531058
  • 397 + 31530661 = 31531058
  • 409 + 31530649 = 31531058
  • 421 + 31530637 = 31531058
  • 487 + 31530571 = 31531058
  • 571 + 31530487 = 31531058

Showing the first eight; more decompositions exist.
