Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981282, here are decompositions:

11 + 981271 = 981282
19 + 981263 = 981282
41 + 981241 = 981282
61 + 981221 = 981282
73 + 981209 = 981282
83 + 981199 = 981282
109 + 981173 = 981282
131 + 981151 = 981282

Showing the first eight; more decompositions exist.
