Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478270, here are decompositions:

11 + 478259 = 478270
17 + 478253 = 478270
29 + 478241 = 478270
71 + 478199 = 478270
101 + 478169 = 478270
113 + 478157 = 478270
131 + 478139 = 478270
269 + 478001 = 478270

Showing the first eight; more decompositions exist.
