Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994820, here are decompositions:

  • 13 + 4294994807 = 4294994820
  • 29 + 4294994791 = 4294994820
  • 73 + 4294994747 = 4294994820
  • 79 + 4294994741 = 4294994820
  • 107 + 4294994713 = 4294994820
  • 331 + 4294994489 = 4294994820
  • 397 + 4294994423 = 4294994820
  • 421 + 4294994399 = 4294994820

Showing the first eight; more decompositions exist.
