Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981328, here are decompositions:

17 + 981311 = 981328
41 + 981287 = 981328
107 + 981221 = 981328
191 + 981137 = 981328
251 + 981077 = 981328
311 + 981017 = 981328
317 + 981011 = 981328
419 + 980909 = 981328

Showing the first eight; more decompositions exist.
