Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491038, here are decompositions:

47 + 490991 = 491038
71 + 490967 = 491038
89 + 490949 = 491038
101 + 490937 = 491038
179 + 490859 = 491038
269 + 490769 = 491038
419 + 490619 = 491038
461 + 490577 = 491038

Showing the first eight; more decompositions exist.
