Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498650, here are decompositions:

3 + 498647 = 498650
7 + 498643 = 498650
37 + 498613 = 498650
67 + 498583 = 498650
73 + 498577 = 498650
127 + 498523 = 498650
157 + 498493 = 498650
181 + 498469 = 498650

Showing the first eight; more decompositions exist.
