Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000628, here are decompositions:

7 + 1000621 = 1000628
19 + 1000609 = 1000628
199 + 1000429 = 1000628
271 + 1000357 = 1000628
337 + 1000291 = 1000628
379 + 1000249 = 1000628
397 + 1000231 = 1000628
457 + 1000171 = 1000628

Showing the first eight; more decompositions exist.
