Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991854, here are decompositions:

37 + 991817 = 991854
43 + 991811 = 991854
103 + 991751 = 991854
113 + 991741 = 991854
131 + 991723 = 991854
137 + 991717 = 991854
151 + 991703 = 991854
191 + 991663 = 991854

Showing the first eight; more decompositions exist.
