Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978478, here are decompositions:

79 + 4294978399 = 4294978478
97 + 4294978381 = 4294978478
151 + 4294978327 = 4294978478
229 + 4294978249 = 4294978478
277 + 4294978201 = 4294978478
331 + 4294978147 = 4294978478
397 + 4294978081 = 4294978478
421 + 4294978057 = 4294978478

Showing the first eight; more decompositions exist.
