Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295002728, here are decompositions:

  • 7 + 4295002721 = 4295002728
  • 31 + 4295002697 = 4295002728
  • 131 + 4295002597 = 4295002728
  • 199 + 4295002529 = 4295002728
  • 227 + 4295002501 = 4295002728
  • 349 + 4295002379 = 4295002728
  • 389 + 4295002339 = 4295002728
  • 439 + 4295002289 = 4295002728

Showing the first eight; more decompositions exist.
