Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991736, here are decompositions:

3 + 991733 = 991736
13 + 991723 = 991736
19 + 991717 = 991736
43 + 991693 = 991736
73 + 991663 = 991736
103 + 991633 = 991736
157 + 991579 = 991736
283 + 991453 = 991736

Showing the first eight; more decompositions exist.
