Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961978, here are decompositions:

19 + 4294961959 = 4294961978
37 + 4294961941 = 4294961978
211 + 4294961767 = 4294961978
271 + 4294961707 = 4294961978
457 + 4294961521 = 4294961978
577 + 4294961401 = 4294961978
661 + 4294961317 = 4294961978
691 + 4294961287 = 4294961978

Showing the first eight; more decompositions exist.
