Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499138, here are decompositions:

5 + 499133 = 499138
11 + 499127 = 499138
71 + 499067 = 499138
149 + 498989 = 499138
191 + 498947 = 499138
257 + 498881 = 499138
281 + 498857 = 499138
347 + 498791 = 499138

Showing the first eight; more decompositions exist.
