Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544576, here are decompositions:

  • 3 + 31544573 = 31544576
  • 43 + 31544533 = 31544576
  • 67 + 31544509 = 31544576
  • 229 + 31544347 = 31544576
  • 397 + 31544179 = 31544576
  • 409 + 31544167 = 31544576
  • 487 + 31544089 = 31544576
  • 499 + 31544077 = 31544576

Showing the first eight; more decompositions exist.
