Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978440, here are decompositions:

41 + 4294978399 = 4294978440
59 + 4294978381 = 4294978440
79 + 4294978361 = 4294978440
107 + 4294978333 = 4294978440
113 + 4294978327 = 4294978440
127 + 4294978313 = 4294978440
131 + 4294978309 = 4294978440
157 + 4294978283 = 4294978440

Showing the first eight; more decompositions exist.
