Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978790, here are decompositions:

13 + 4294978777 = 4294978790
61 + 4294978729 = 4294978790
163 + 4294978627 = 4294978790
199 + 4294978591 = 4294978790
409 + 4294978381 = 4294978790
457 + 4294978333 = 4294978790
463 + 4294978327 = 4294978790
541 + 4294978249 = 4294978790

Showing the first eight; more decompositions exist.
