Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490970, here are decompositions:

3 + 490967 = 490970
13 + 490957 = 490970
19 + 490951 = 490970
43 + 490927 = 490970
79 + 490891 = 490970
199 + 490771 = 490970
229 + 490741 = 490970
307 + 490663 = 490970

Showing the first eight; more decompositions exist.
