Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491074, here are decompositions:

71 + 491003 = 491074
83 + 490991 = 491074
107 + 490967 = 491074
137 + 490937 = 491074
197 + 490877 = 491074
431 + 490643 = 491074
443 + 490631 = 491074
503 + 490571 = 491074

Showing the first eight; more decompositions exist.
