Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985722, here are decompositions:

13 + 985709 = 985722
19 + 985703 = 985722
43 + 985679 = 985722
83 + 985639 = 985722
109 + 985613 = 985722
151 + 985571 = 985722
191 + 985531 = 985722
193 + 985529 = 985722

Showing the first eight; more decompositions exist.
