Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560048, here are decompositions:

  • 19 + 31560029 = 31560048
  • 29 + 31560019 = 31560048
  • 59 + 31559989 = 31560048
  • 67 + 31559981 = 31560048
  • 71 + 31559977 = 31560048
  • 97 + 31559951 = 31560048
  • 137 + 31559911 = 31560048
  • 197 + 31559851 = 31560048

Showing the first eight; more decompositions exist.
