Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974778, here are decompositions:

41 + 4294974737 = 4294974778
47 + 4294974731 = 4294974778
131 + 4294974647 = 4294974778
137 + 4294974641 = 4294974778
179 + 4294974599 = 4294974778
197 + 4294974581 = 4294974778
251 + 4294974527 = 4294974778
491 + 4294974287 = 4294974778

Showing the first eight; more decompositions exist.
