Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981204, here are decompositions:

5 + 981199 = 981204
17 + 981187 = 981204
31 + 981173 = 981204
53 + 981151 = 981204
67 + 981137 = 981204
71 + 981133 = 981204
113 + 981091 = 981204
127 + 981077 = 981204

Showing the first eight; more decompositions exist.
