Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976780, here are decompositions:

  • 7 + 4294976773 = 4294976780
  • 37 + 4294976743 = 4294976780
  • 103 + 4294976677 = 4294976780
  • 163 + 4294976617 = 4294976780
  • 349 + 4294976431 = 4294976780
  • 397 + 4294976383 = 4294976780
  • 421 + 4294976359 = 4294976780
  • 433 + 4294976347 = 4294976780

Showing the first eight; more decompositions exist.
