Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976978, here are decompositions:

37 + 4294976941 = 4294976978
139 + 4294976839 = 4294976978
181 + 4294976797 = 4294976978
547 + 4294976431 = 4294976978
619 + 4294976359 = 4294976978
631 + 4294976347 = 4294976978
709 + 4294976269 = 4294976978
757 + 4294976221 = 4294976978

Showing the first eight; more decompositions exist.
