Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994778, here are decompositions:

31 + 4294994747 = 4294994778
37 + 4294994741 = 4294994778
127 + 4294994651 = 4294994778
379 + 4294994399 = 4294994778
401 + 4294994377 = 4294994778
421 + 4294994357 = 4294994778
439 + 4294994339 = 4294994778
449 + 4294994329 = 4294994778

Showing the first eight; more decompositions exist.
