Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981324, here are decompositions:

5 + 981319 = 981324
13 + 981311 = 981324
23 + 981301 = 981324
37 + 981287 = 981324
41 + 981283 = 981324
53 + 981271 = 981324
61 + 981263 = 981324
83 + 981241 = 981324

Showing the first eight; more decompositions exist.
