Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003918, here are decompositions:

5 + 1003913 = 1003918
11 + 1003907 = 1003918
29 + 1003889 = 1003918
101 + 1003817 = 1003918
131 + 1003787 = 1003918
239 + 1003679 = 1003918
317 + 1003601 = 1003918
401 + 1003517 = 1003918

Showing the first eight; more decompositions exist.
