Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981362, here are decompositions:

43 + 981319 = 981362
61 + 981301 = 981362
73 + 981289 = 981362
79 + 981283 = 981362
163 + 981199 = 981362
211 + 981151 = 981362
223 + 981139 = 981362
229 + 981133 = 981362

Showing the first eight; more decompositions exist.
