Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490242, here are decompositions:

19 + 490223 = 490242
41 + 490201 = 490242
59 + 490183 = 490242
73 + 490169 = 490242
83 + 490159 = 490242
131 + 490111 = 490242
139 + 490103 = 490242
211 + 490031 = 490242

Showing the first eight; more decompositions exist.
