Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492720, here are decompositions:

13 + 492707 = 492720
47 + 492673 = 492720
61 + 492659 = 492720
73 + 492647 = 492720
79 + 492641 = 492720
89 + 492631 = 492720
101 + 492619 = 492720
103 + 492617 = 492720

Showing the first eight; more decompositions exist.
