Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492980, here are decompositions:

13 + 492967 = 492980
79 + 492901 = 492980
97 + 492883 = 492980
109 + 492871 = 492980
127 + 492853 = 492980
181 + 492799 = 492980
199 + 492781 = 492980
211 + 492769 = 492980

Showing the first eight; more decompositions exist.
