Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478850, here are decompositions:

7 + 478843 = 478850
19 + 478831 = 478850
37 + 478813 = 478850
103 + 478747 = 478850
109 + 478741 = 478850
139 + 478711 = 478850
199 + 478651 = 478850
223 + 478627 = 478850

Showing the first eight; more decompositions exist.
