Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072778, here are decompositions:

37 + 4295072741 = 4295072778
89 + 4295072689 = 4295072778
97 + 4295072681 = 4295072778
109 + 4295072669 = 4295072778
167 + 4295072611 = 4295072778
181 + 4295072597 = 4295072778
349 + 4295072429 = 4295072778
509 + 4295072269 = 4295072778

Showing the first eight; more decompositions exist.
