Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974978, here are decompositions:

5 + 4294974973 = 4294974978
59 + 4294974919 = 4294974978
61 + 4294974917 = 4294974978
97 + 4294974881 = 4294974978
167 + 4294974811 = 4294974978
241 + 4294974737 = 4294974978
331 + 4294974647 = 4294974978
337 + 4294974641 = 4294974978

Showing the first eight; more decompositions exist.
