Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478206, here are decompositions:

7 + 478199 = 478206
17 + 478189 = 478206
37 + 478169 = 478206
67 + 478139 = 478206
107 + 478099 = 478206
137 + 478069 = 478206
139 + 478067 = 478206
167 + 478039 = 478206

Showing the first eight; more decompositions exist.
