Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972820, here are decompositions:

  • 13 + 4294972807 = 4294972820
  • 31 + 4294972789 = 4294972820
  • 157 + 4294972663 = 4294972820
  • 163 + 4294972657 = 4294972820
  • 211 + 4294972609 = 4294972820
  • 241 + 4294972579 = 4294972820
  • 379 + 4294972441 = 4294972820
  • 409 + 4294972411 = 4294972820

Showing the first eight; more decompositions exist.
