Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981522, here are decompositions:

5 + 981517 = 981522
29 + 981493 = 981522
41 + 981481 = 981522
71 + 981451 = 981522
79 + 981443 = 981522
83 + 981439 = 981522
103 + 981419 = 981522
131 + 981391 = 981522

Showing the first eight; more decompositions exist.
