Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478978, here are decompositions:

11 + 478967 = 478978
41 + 478937 = 478978
47 + 478931 = 478978
107 + 478871 = 478978
167 + 478811 = 478978
191 + 478787 = 478978
239 + 478739 = 478978
251 + 478727 = 478978

Showing the first eight; more decompositions exist.
