Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295055640, here are decompositions:

3 + 4295055637 = 4295055640
11 + 4295055629 = 4295055640
17 + 4295055623 = 4295055640
23 + 4295055617 = 4295055640
89 + 4295055551 = 4295055640
173 + 4295055467 = 4295055640
179 + 4295055461 = 4295055640
311 + 4295055329 = 4295055640

Showing the first eight; more decompositions exist.
