Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492800, here are decompositions:

19 + 492781 = 492800
31 + 492769 = 492800
37 + 492763 = 492800
43 + 492757 = 492800
79 + 492721 = 492800
127 + 492673 = 492800
181 + 492619 = 492800
199 + 492601 = 492800

Showing the first eight; more decompositions exist.
