Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981302, here are decompositions:

13 + 981289 = 981302
19 + 981283 = 981302
31 + 981271 = 981302
61 + 981241 = 981302
103 + 981199 = 981302
151 + 981151 = 981302
163 + 981139 = 981302
211 + 981091 = 981302

Showing the first eight; more decompositions exist.
