Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987478, here are decompositions:

337 + 4294987141 = 4294987478
367 + 4294987111 = 4294987478
421 + 4294987057 = 4294987478
487 + 4294986991 = 4294987478
571 + 4294986907 = 4294987478
829 + 4294986649 = 4294987478
967 + 4294986511 = 4294987478
1039 + 4294986439 = 4294987478

Showing the first eight; more decompositions exist.
