Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997478, here are decompositions:

7 + 4294997471 = 4294997478
17 + 4294997461 = 4294997478
61 + 4294997417 = 4294997478
89 + 4294997389 = 4294997478
181 + 4294997297 = 4294997478
197 + 4294997281 = 4294997478
257 + 4294997221 = 4294997478
281 + 4294997197 = 4294997478

Showing the first eight; more decompositions exist.
