Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532126, here are decompositions:

  • 13 + 31532113 = 31532126
  • 37 + 31532089 = 31532126
  • 313 + 31531813 = 31532126
  • 487 + 31531639 = 31532126
  • 499 + 31531627 = 31532126
  • 547 + 31531579 = 31532126
  • 643 + 31531483 = 31532126
  • 673 + 31531453 = 31532126

Showing the first eight; more decompositions exist.
