Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295028978, here are decompositions:

127 + 4295028851 = 4295028978
167 + 4295028811 = 4295028978
199 + 4295028779 = 4295028978
271 + 4295028707 = 4295028978
367 + 4295028611 = 4295028978
379 + 4295028599 = 4295028978
571 + 4295028407 = 4295028978
677 + 4295028301 = 4295028978

Showing the first eight; more decompositions exist.
