Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020494, here are decompositions:

3 + 1020491 = 1020494
37 + 1020457 = 1020494
43 + 1020451 = 1020494
157 + 1020337 = 1020494
193 + 1020301 = 1020494
271 + 1020223 = 1020494
331 + 1020163 = 1020494
337 + 1020157 = 1020494

Showing the first eight; more decompositions exist.
