Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981192, here are decompositions:

5 + 981187 = 981192
19 + 981173 = 981192
41 + 981151 = 981192
53 + 981139 = 981192
59 + 981133 = 981192
101 + 981091 = 981192
131 + 981061 = 981192
181 + 981011 = 981192

Showing the first eight; more decompositions exist.
