Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560076, here are decompositions:

  • 3 + 31560073 = 31560076
  • 17 + 31560059 = 31560076
  • 29 + 31560047 = 31560076
  • 47 + 31560029 = 31560076
  • 227 + 31559849 = 31560076
  • 263 + 31559813 = 31560076
  • 293 + 31559783 = 31560076
  • 389 + 31559687 = 31560076

Showing the first eight; more decompositions exist.
