Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988778, here are decompositions:

5 + 4294988773 = 4294988778
71 + 4294988707 = 4294988778
79 + 4294988699 = 4294988778
89 + 4294988689 = 4294988778
137 + 4294988641 = 4294988778
349 + 4294988429 = 4294988778
359 + 4294988419 = 4294988778
401 + 4294988377 = 4294988778

Showing the first eight; more decompositions exist.
