Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294996728, here are decompositions:

  • 19 + 4294996709 = 4294996728
  • 41 + 4294996687 = 4294996728
  • 131 + 4294996597 = 4294996728
  • 149 + 4294996579 = 4294996728
  • 179 + 4294996549 = 4294996728
  • 401 + 4294996327 = 4294996728
  • 409 + 4294996319 = 4294996728
  • 461 + 4294996267 = 4294996728

Showing the first eight; more decompositions exist.
