Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492872, here are decompositions:

19 + 492853 = 492872
73 + 492799 = 492872
103 + 492769 = 492872
109 + 492763 = 492872
151 + 492721 = 492872
199 + 492673 = 492872
241 + 492631 = 492872
271 + 492601 = 492872

Showing the first eight; more decompositions exist.
