Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981552, here are decompositions:

29 + 981523 = 981552
59 + 981493 = 981552
71 + 981481 = 981552
79 + 981473 = 981552
101 + 981451 = 981552
109 + 981443 = 981552
113 + 981439 = 981552
179 + 981373 = 981552

Showing the first eight; more decompositions exist.
