Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981246, here are decompositions:

5 + 981241 = 981246
37 + 981209 = 981246
47 + 981199 = 981246
59 + 981187 = 981246
73 + 981173 = 981246
107 + 981139 = 981246
109 + 981137 = 981246
113 + 981133 = 981246

Showing the first eight; more decompositions exist.
