Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498988, here are decompositions:

11 + 498977 = 498988
41 + 498947 = 498988
107 + 498881 = 498988
131 + 498857 = 498988
197 + 498791 = 498988
227 + 498761 = 498988
239 + 498749 = 498988
389 + 498599 = 498988

Showing the first eight; more decompositions exist.
