Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957978, here are decompositions:

5 + 4294957973 = 4294957978
137 + 4294957841 = 4294957978
197 + 4294957781 = 4294957978
281 + 4294957697 = 4294957978
659 + 4294957319 = 4294957978
821 + 4294957157 = 4294957978
911 + 4294957067 = 4294957978
1097 + 4294956881 = 4294957978

Showing the first eight; more decompositions exist.
