Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492578, here are decompositions:

67 + 492511 = 492578
157 + 492421 = 492578
181 + 492397 = 492578
571 + 492007 = 492578
601 + 491977 = 492578
727 + 491851 = 492578
859 + 491719 = 492578
967 + 491611 = 492578

Showing the first eight; more decompositions exist.
