Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492780, here are decompositions:

11 + 492769 = 492780
17 + 492763 = 492780
19 + 492761 = 492780
23 + 492757 = 492780
59 + 492721 = 492780
61 + 492719 = 492780
73 + 492707 = 492780
107 + 492673 = 492780

Showing the first eight; more decompositions exist.
