Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985630, here are decompositions:

17 + 985613 = 985630
29 + 985601 = 985630
59 + 985571 = 985630
83 + 985547 = 985630
101 + 985529 = 985630
131 + 985499 = 985630
137 + 985493 = 985630
167 + 985463 = 985630

Showing the first eight; more decompositions exist.
