Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492572, here are decompositions:

61 + 492511 = 492572
109 + 492463 = 492572
151 + 492421 = 492572
163 + 492409 = 492572
673 + 491899 = 492572
739 + 491833 = 492572
853 + 491719 = 492572
919 + 491653 = 492572

Showing the first eight; more decompositions exist.
