Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987838, here are decompositions:

67 + 4294987771 = 4294987838
157 + 4294987681 = 4294987838
277 + 4294987561 = 4294987838
607 + 4294987231 = 4294987838
727 + 4294987111 = 4294987838
787 + 4294987051 = 4294987838
1291 + 4294986547 = 4294987838
1327 + 4294986511 = 4294987838

Showing the first eight; more decompositions exist.
