Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986520, here are decompositions:

11 + 986509 = 986520
13 + 986507 = 986520
23 + 986497 = 986520
43 + 986477 = 986520
83 + 986437 = 986520
103 + 986417 = 986520
109 + 986411 = 986520
151 + 986369 = 986520

Showing the first eight; more decompositions exist.
