Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295028990, here are decompositions:

  • 103 + 4295028887 = 4295028990
  • 139 + 4295028851 = 4295028990
  • 173 + 4295028817 = 4295028990
  • 179 + 4295028811 = 4295028990
  • 199 + 4295028791 = 4295028990
  • 211 + 4295028779 = 4295028990
  • 233 + 4295028757 = 4295028990
  • 271 + 4295028719 = 4295028990

Showing the first eight; more decompositions exist.
