Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295019978, here are decompositions:

31 + 4295019947 = 4295019978
71 + 4295019907 = 4295019978
107 + 4295019871 = 4295019978
127 + 4295019851 = 4295019978
167 + 4295019811 = 4295019978
199 + 4295019779 = 4295019978
211 + 4295019767 = 4295019978
311 + 4295019667 = 4295019978

Showing the first eight; more decompositions exist.
