Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981712, here are decompositions:

5 + 981707 = 981712
29 + 981683 = 981712
59 + 981653 = 981712
89 + 981623 = 981712
113 + 981599 = 981712
239 + 981473 = 981712
269 + 981443 = 981712
293 + 981419 = 981712

Showing the first eight; more decompositions exist.
