Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478846, here are decompositions:

3 + 478843 = 478846
23 + 478823 = 478846
59 + 478787 = 478846
83 + 478763 = 478846
107 + 478739 = 478846
149 + 478697 = 478846
167 + 478679 = 478846
257 + 478589 = 478846

Showing the first eight; more decompositions exist.
