Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991662, here are decompositions:

11 + 991651 = 991662
19 + 991643 = 991662
29 + 991633 = 991662
41 + 991621 = 991662
43 + 991619 = 991662
59 + 991603 = 991662
83 + 991579 = 991662
131 + 991531 = 991662

Showing the first eight; more decompositions exist.
