Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295012720, here are decompositions:

3 + 4295012717 = 4295012720
43 + 4295012677 = 4295012720
67 + 4295012653 = 4295012720
73 + 4295012647 = 4295012720
139 + 4295012581 = 4295012720
181 + 4295012539 = 4295012720
283 + 4295012437 = 4295012720
337 + 4295012383 = 4295012720

Showing the first eight; more decompositions exist.
