Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499198, here are decompositions:

17 + 499181 = 499198
41 + 499157 = 499198
47 + 499151 = 499198
59 + 499139 = 499198
71 + 499127 = 499198
131 + 499067 = 499198
251 + 498947 = 499198
317 + 498881 = 499198

Showing the first eight; more decompositions exist.
