Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478318, here are decompositions:

47 + 478271 = 478318
59 + 478259 = 478318
149 + 478169 = 478318
179 + 478139 = 478318
251 + 478067 = 478318
317 + 478001 = 478318
419 + 477899 = 478318
461 + 477857 = 478318

Showing the first eight; more decompositions exist.
