Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492920, here are decompositions:

19 + 492901 = 492920
37 + 492883 = 492920
67 + 492853 = 492920
139 + 492781 = 492920
151 + 492769 = 492920
157 + 492763 = 492920
163 + 492757 = 492920
199 + 492721 = 492920

Showing the first eight; more decompositions exist.
