Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981528, here are decompositions:

5 + 981523 = 981528
11 + 981517 = 981528
47 + 981481 = 981528
61 + 981467 = 981528
89 + 981439 = 981528
109 + 981419 = 981528
131 + 981397 = 981528
137 + 981391 = 981528

Showing the first eight; more decompositions exist.
