Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978400, here are decompositions:

19 + 4294978381 = 4294978400
67 + 4294978333 = 4294978400
73 + 4294978327 = 4294978400
151 + 4294978249 = 4294978400
199 + 4294978201 = 4294978400
277 + 4294978123 = 4294978400
313 + 4294978087 = 4294978400
367 + 4294978033 = 4294978400

Showing the first eight; more decompositions exist.
