Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973840, here are decompositions:

97 + 4294973743 = 4294973840
127 + 4294973713 = 4294973840
211 + 4294973629 = 4294973840
229 + 4294973611 = 4294973840
271 + 4294973569 = 4294973840
433 + 4294973407 = 4294973840
457 + 4294973383 = 4294973840
607 + 4294973233 = 4294973840

Showing the first eight; more decompositions exist.
