Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491634, here are decompositions:

7 + 491627 = 491634
23 + 491611 = 491634
41 + 491593 = 491634
43 + 491591 = 491634
53 + 491581 = 491634
97 + 491537 = 491634
103 + 491531 = 491634
107 + 491527 = 491634

Showing the first eight; more decompositions exist.
