Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491622, here are decompositions:

11 + 491611 = 491622
29 + 491593 = 491622
31 + 491591 = 491622
41 + 491581 = 491622
83 + 491539 = 491622
139 + 491483 = 491622
193 + 491429 = 491622
199 + 491423 = 491622

Showing the first eight; more decompositions exist.
