Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574522, here are decompositions:

  • 43 + 31574479 = 31574522
  • 73 + 31574449 = 31574522
  • 79 + 31574443 = 31574522
  • 103 + 31574419 = 31574522
  • 193 + 31574329 = 31574522
  • 349 + 31574173 = 31574522
  • 523 + 31573999 = 31574522
  • 691 + 31573831 = 31574522

Showing the first eight; more decompositions exist.
