Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445062, here are decompositions:

  • 29 + 31445033 = 31445062
  • 53 + 31445009 = 31445062
  • 191 + 31444871 = 31445062
  • 401 + 31444661 = 31445062
  • 419 + 31444643 = 31445062
  • 431 + 31444631 = 31445062
  • 503 + 31444559 = 31445062
  • 521 + 31444541 = 31445062

Showing the first eight; more decompositions exist.
