Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003388, here are decompositions:

7 + 1003381 = 1003388
19 + 1003369 = 1003388
37 + 1003351 = 1003388
97 + 1003291 = 1003388
109 + 1003279 = 1003388
277 + 1003111 = 1003388
349 + 1003039 = 1003388
409 + 1002979 = 1003388

Showing the first eight; more decompositions exist.
