Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491592, here are decompositions:

11 + 491581 = 491592
53 + 491539 = 491592
61 + 491531 = 491592
89 + 491503 = 491592
103 + 491489 = 491592
109 + 491483 = 491592
131 + 491461 = 491592
163 + 491429 = 491592

Showing the first eight; more decompositions exist.
