Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499018, here are decompositions:

29 + 498989 = 499018
41 + 498977 = 499018
71 + 498947 = 499018
137 + 498881 = 499018
227 + 498791 = 499018
239 + 498779 = 499018
251 + 498767 = 499018
257 + 498761 = 499018

Showing the first eight; more decompositions exist.
