Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478250, here are decompositions:

7 + 478243 = 478250
37 + 478213 = 478250
43 + 478207 = 478250
61 + 478189 = 478250
79 + 478171 = 478250
139 + 478111 = 478250
151 + 478099 = 478250
163 + 478087 = 478250

Showing the first eight; more decompositions exist.
