Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492688, here are decompositions:

17 + 492671 = 492688
29 + 492659 = 492688
41 + 492647 = 492688
47 + 492641 = 492688
59 + 492629 = 492688
71 + 492617 = 492688
101 + 492587 = 492688
137 + 492551 = 492688

Showing the first eight; more decompositions exist.
