Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492090, here are decompositions:

7 + 492083 = 492090
13 + 492077 = 492090
23 + 492067 = 492090
29 + 492061 = 492090
31 + 492059 = 492090
37 + 492053 = 492090
43 + 492047 = 492090
61 + 492029 = 492090

Showing the first eight; more decompositions exist.
