Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981510, here are decompositions:

17 + 981493 = 981510
29 + 981481 = 981510
37 + 981473 = 981510
43 + 981467 = 981510
59 + 981451 = 981510
67 + 981443 = 981510
71 + 981439 = 981510
73 + 981437 = 981510

Showing the first eight; more decompositions exist.
