Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994478, here are decompositions:

29 + 4294994449 = 4294994478
79 + 4294994399 = 4294994478
101 + 4294994377 = 4294994478
107 + 4294994371 = 4294994478
139 + 4294994339 = 4294994478
149 + 4294994329 = 4294994478
167 + 4294994311 = 4294994478
311 + 4294994167 = 4294994478

Showing the first eight; more decompositions exist.
