Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294989478, here are decompositions:

5 + 4294989473 = 4294989478
41 + 4294989437 = 4294989478
107 + 4294989371 = 4294989478
251 + 4294989227 = 4294989478
257 + 4294989221 = 4294989478
317 + 4294989161 = 4294989478
587 + 4294988891 = 4294989478
599 + 4294988879 = 4294989478

Showing the first eight; more decompositions exist.
