Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295007978, here are decompositions:

29 + 4295007949 = 4295007978
31 + 4295007947 = 4295007978
59 + 4295007919 = 4295007978
71 + 4295007907 = 4295007978
97 + 4295007881 = 4295007978
109 + 4295007869 = 4295007978
139 + 4295007839 = 4295007978
167 + 4295007811 = 4295007978

Showing the first eight; more decompositions exist.
