Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978436, here are decompositions:

37 + 4294978399 = 4294978436
103 + 4294978333 = 4294978436
109 + 4294978327 = 4294978436
127 + 4294978309 = 4294978436
313 + 4294978123 = 4294978436
349 + 4294978087 = 4294978436
379 + 4294978057 = 4294978436
409 + 4294978027 = 4294978436

Showing the first eight; more decompositions exist.
