Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985680, here are decompositions:

  • 23 + 4294985657 = 4294985680
  • 149 + 4294985531 = 4294985680
  • 281 + 4294985399 = 4294985680
  • 347 + 4294985333 = 4294985680
  • 389 + 4294985291 = 4294985680
  • 443 + 4294985237 = 4294985680
  • 647 + 4294985033 = 4294985680
  • 653 + 4294985027 = 4294985680

Showing the first eight; more decompositions exist.
