Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991706, here are decompositions:

3 + 991703 = 991706
13 + 991693 = 991706
43 + 991663 = 991706
73 + 991633 = 991706
103 + 991603 = 991706
127 + 991579 = 991706
139 + 991567 = 991706
223 + 991483 = 991706

Showing the first eight; more decompositions exist.
