Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492784, here are decompositions:

3 + 492781 = 492784
23 + 492761 = 492784
53 + 492731 = 492784
113 + 492671 = 492784
137 + 492647 = 492784
167 + 492617 = 492784
197 + 492587 = 492784
233 + 492551 = 492784

Showing the first eight; more decompositions exist.
