Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295012778, here are decompositions:

29 + 4295012749 = 4295012778
37 + 4295012741 = 4295012778
61 + 4295012717 = 4295012778
101 + 4295012677 = 4295012778
131 + 4295012647 = 4295012778
149 + 4295012629 = 4295012778
151 + 4295012627 = 4295012778
157 + 4295012621 = 4295012778

Showing the first eight; more decompositions exist.
