Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000918, here are decompositions:

11 + 1000907 = 1000918
29 + 1000889 = 1000918
59 + 1000859 = 1000918
71 + 1000847 = 1000918
89 + 1000829 = 1000918
197 + 1000721 = 1000918
227 + 1000691 = 1000918
239 + 1000679 = 1000918

Showing the first eight; more decompositions exist.
