Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977428, here are decompositions:

37 + 4294977391 = 4294977428
211 + 4294977217 = 4294977428
331 + 4294977097 = 4294977428
337 + 4294977091 = 4294977428
349 + 4294977079 = 4294977428
487 + 4294976941 = 4294977428
499 + 4294976929 = 4294977428
541 + 4294976887 = 4294977428

Showing the first eight; more decompositions exist.
