Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003628, here are decompositions:

7 + 1003621 = 1003628
19 + 1003609 = 1003628
79 + 1003549 = 1003628
211 + 1003417 = 1003628
277 + 1003351 = 1003628
337 + 1003291 = 1003628
349 + 1003279 = 1003628
487 + 1003141 = 1003628

Showing the first eight; more decompositions exist.
