Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972880, here are decompositions:

  • 13 + 4294972867 = 4294972880
  • 19 + 4294972861 = 4294972880
  • 73 + 4294972807 = 4294972880
  • 223 + 4294972657 = 4294972880
  • 271 + 4294972609 = 4294972880
  • 277 + 4294972603 = 4294972880
  • 313 + 4294972567 = 4294972880
  • 439 + 4294972441 = 4294972880

Showing the first eight; more decompositions exist.
