Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988820, here are decompositions:

  • 19 + 4294988801 = 4294988820
  • 47 + 4294988773 = 4294988820
  • 113 + 4294988707 = 4294988820
  • 127 + 4294988693 = 4294988820
  • 131 + 4294988689 = 4294988820
  • 179 + 4294988641 = 4294988820
  • 211 + 4294988609 = 4294988820
  • 229 + 4294988591 = 4294988820

Showing the first eight; more decompositions exist.
