Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991674, here are decompositions:

11 + 991663 = 991674
23 + 991651 = 991674
31 + 991643 = 991674
41 + 991633 = 991674
53 + 991621 = 991674
67 + 991607 = 991674
71 + 991603 = 991674
107 + 991567 = 991674

Showing the first eight; more decompositions exist.
