Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981308, here are decompositions:

7 + 981301 = 981308
19 + 981289 = 981308
37 + 981271 = 981308
67 + 981241 = 981308
109 + 981199 = 981308
157 + 981151 = 981308
241 + 981067 = 981308
271 + 981037 = 981308

Showing the first eight; more decompositions exist.
