Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977728, here are decompositions:

61 + 4294977667 = 4294977728
157 + 4294977571 = 4294977728
229 + 4294977499 = 4294977728
337 + 4294977391 = 4294977728
631 + 4294977097 = 4294977728
661 + 4294977067 = 4294977728
751 + 4294976977 = 4294977728
787 + 4294976941 = 4294977728

Showing the first eight; more decompositions exist.
