Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498140, here are decompositions:

37 + 498103 = 498140
67 + 498073 = 498140
79 + 498061 = 498140
127 + 498013 = 498140
151 + 497989 = 498140
163 + 497977 = 498140
211 + 497929 = 498140
241 + 497899 = 498140

Showing the first eight; more decompositions exist.
