Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492728, here are decompositions:

7 + 492721 = 492728
97 + 492631 = 492728
109 + 492619 = 492728
127 + 492601 = 492728
241 + 492487 = 492728
307 + 492421 = 492728
331 + 492397 = 492728
409 + 492319 = 492728

Showing the first eight; more decompositions exist.
