Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295019920, here are decompositions:

13 + 4295019907 = 4295019920
109 + 4295019811 = 4295019920
151 + 4295019769 = 4295019920
229 + 4295019691 = 4295019920
271 + 4295019649 = 4295019920
277 + 4295019643 = 4295019920
349 + 4295019571 = 4295019920
409 + 4295019511 = 4295019920

Showing the first eight; more decompositions exist.
