Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981694, here are decompositions:

3 + 981691 = 981694
11 + 981683 = 981694
41 + 981653 = 981694
71 + 981623 = 981694
107 + 981587 = 981694
167 + 981527 = 981694
227 + 981467 = 981694
251 + 981443 = 981694

Showing the first eight; more decompositions exist.
