Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478212, here are decompositions:

5 + 478207 = 478212
13 + 478199 = 478212
23 + 478189 = 478212
41 + 478171 = 478212
43 + 478169 = 478212
73 + 478139 = 478212
83 + 478129 = 478212
101 + 478111 = 478212

Showing the first eight; more decompositions exist.
