Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027490, here are decompositions:

3 + 1027487 = 1027490
7 + 1027483 = 1027490
19 + 1027471 = 1027490
31 + 1027459 = 1027490
73 + 1027417 = 1027490
229 + 1027261 = 1027490
283 + 1027207 = 1027490
337 + 1027153 = 1027490

Showing the first eight; more decompositions exist.
