Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991694, here are decompositions:

31 + 991663 = 991694
43 + 991651 = 991694
61 + 991633 = 991694
73 + 991621 = 991694
127 + 991567 = 991694
163 + 991531 = 991694
211 + 991483 = 991694
241 + 991453 = 991694

Showing the first eight; more decompositions exist.
