Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994780, here are decompositions:

  • 67 + 4294994713 = 4294994780
  • 79 + 4294994701 = 4294994780
  • 163 + 4294994617 = 4294994780
  • 331 + 4294994449 = 4294994780
  • 409 + 4294994371 = 4294994780
  • 463 + 4294994317 = 4294994780
  • 547 + 4294994233 = 4294994780
  • 577 + 4294994203 = 4294994780

Showing the first eight; more decompositions exist.
