Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981356, here are decompositions:

37 + 981319 = 981356
67 + 981289 = 981356
73 + 981283 = 981356
157 + 981199 = 981356
223 + 981133 = 981356
283 + 981073 = 981356
307 + 981049 = 981356
457 + 980899 = 981356

Showing the first eight; more decompositions exist.
