Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987812, here are decompositions:

  • 13 + 4294987799 = 4294987812
  • 41 + 4294987771 = 4294987812
  • 43 + 4294987769 = 4294987812
  • 61 + 4294987751 = 4294987812
  • 109 + 4294987703 = 4294987812
  • 131 + 4294987681 = 4294987812
  • 191 + 4294987621 = 4294987812
  • 223 + 4294987589 = 4294987812

Showing the first eight; more decompositions exist.
