Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981634, here are decompositions:

11 + 981623 = 981634
47 + 981587 = 981634
107 + 981527 = 981634
167 + 981467 = 981634
191 + 981443 = 981634
197 + 981437 = 981634
257 + 981377 = 981634
347 + 981287 = 981634

Showing the first eight; more decompositions exist.
