Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492642, here are decompositions:

11 + 492631 = 492642
13 + 492629 = 492642
23 + 492619 = 492642
41 + 492601 = 492642
79 + 492563 = 492642
131 + 492511 = 492642
151 + 492491 = 492642
179 + 492463 = 492642

Showing the first eight; more decompositions exist.
