Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981532, here are decompositions:

5 + 981527 = 981532
59 + 981473 = 981532
89 + 981443 = 981532
113 + 981419 = 981532
269 + 981263 = 981532
311 + 981221 = 981532
359 + 981173 = 981532
509 + 981023 = 981532

Showing the first eight; more decompositions exist.
