Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972720, here are decompositions:

107 + 4294972613 = 4294972720
239 + 4294972481 = 4294972720
383 + 4294972337 = 4294972720
569 + 4294972151 = 4294972720
641 + 4294972079 = 4294972720
659 + 4294972061 = 4294972720
683 + 4294972037 = 4294972720
1163 + 4294971557 = 4294972720

Showing the first eight; more decompositions exist.
