Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490188, here are decompositions:

5 + 490183 = 490188
19 + 490169 = 490188
29 + 490159 = 490188
37 + 490151 = 490188
67 + 490121 = 490188
71 + 490117 = 490188
131 + 490057 = 490188
157 + 490031 = 490188

Showing the first eight; more decompositions exist.
