Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499180, here are decompositions:

23 + 499157 = 499180
29 + 499151 = 499180
41 + 499139 = 499180
47 + 499133 = 499180
53 + 499127 = 499180
113 + 499067 = 499180
191 + 498989 = 499180
233 + 498947 = 499180

Showing the first eight; more decompositions exist.
