Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490230, here are decompositions:

7 + 490223 = 490230
23 + 490207 = 490230
29 + 490201 = 490230
47 + 490183 = 490230
61 + 490169 = 490230
71 + 490159 = 490230
79 + 490151 = 490230
109 + 490121 = 490230

Showing the first eight; more decompositions exist.
