Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478912, here are decompositions:

11 + 478901 = 478912
41 + 478871 = 478912
59 + 478853 = 478912
89 + 478823 = 478912
101 + 478811 = 478912
149 + 478763 = 478912
173 + 478739 = 478912
233 + 478679 = 478912

Showing the first eight; more decompositions exist.
