Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478550, here are decompositions:

19 + 478531 = 478550
67 + 478483 = 478550
97 + 478453 = 478550
109 + 478441 = 478550
139 + 478411 = 478550
151 + 478399 = 478550
199 + 478351 = 478550
211 + 478339 = 478550

Showing the first eight; more decompositions exist.
