Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991752, here are decompositions:

11 + 991741 = 991752
19 + 991733 = 991752
29 + 991723 = 991752
59 + 991693 = 991752
89 + 991663 = 991752
101 + 991651 = 991752
109 + 991643 = 991752
131 + 991621 = 991752

Showing the first eight; more decompositions exist.
