Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490220, here are decompositions:

13 + 490207 = 490220
19 + 490201 = 490220
37 + 490183 = 490220
61 + 490159 = 490220
103 + 490117 = 490220
109 + 490111 = 490220
163 + 490057 = 490220
277 + 489943 = 490220

Showing the first eight; more decompositions exist.
