Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576446, here are decompositions:

  • 7 + 31576439 = 31576446
  • 19 + 31576427 = 31576446
  • 29 + 31576417 = 31576446
  • 37 + 31576409 = 31576446
  • 43 + 31576403 = 31576446
  • 73 + 31576373 = 31576446
  • 79 + 31576367 = 31576446
  • 157 + 31576289 = 31576446

Showing the first eight; more decompositions exist.
