Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987818, here are decompositions:

  • 19 + 4294987799 = 4294987818
  • 47 + 4294987771 = 4294987818
  • 61 + 4294987757 = 4294987818
  • 67 + 4294987751 = 4294987818
  • 137 + 4294987681 = 4294987818
  • 167 + 4294987651 = 4294987818
  • 197 + 4294987621 = 4294987818
  • 211 + 4294987607 = 4294987818

Showing the first eight; more decompositions exist.
