Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478502, here are decompositions:

19 + 478483 = 478502
43 + 478459 = 478502
61 + 478441 = 478502
103 + 478399 = 478502
151 + 478351 = 478502
163 + 478339 = 478502
181 + 478321 = 478502
229 + 478273 = 478502

Showing the first eight; more decompositions exist.
