Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981322, here are decompositions:

3 + 981319 = 981322
11 + 981311 = 981322
59 + 981263 = 981322
101 + 981221 = 981322
113 + 981209 = 981322
149 + 981173 = 981322
311 + 981011 = 981322
359 + 980963 = 981322

Showing the first eight; more decompositions exist.
