Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020530, here are decompositions:

13 + 1020517 = 1020530
73 + 1020457 = 1020530
79 + 1020451 = 1020530
151 + 1020379 = 1020530
193 + 1020337 = 1020530
229 + 1020301 = 1020530
271 + 1020259 = 1020530
283 + 1020247 = 1020530

Showing the first eight; more decompositions exist.
