Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971978, here are decompositions:

41 + 4294971937 = 4294971978
47 + 4294971931 = 4294971978
137 + 4294971841 = 4294971978
149 + 4294971829 = 4294971978
197 + 4294971781 = 4294971978
421 + 4294971557 = 4294971978
487 + 4294971491 = 4294971978
509 + 4294971469 = 4294971978

Showing the first eight; more decompositions exist.
