Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981732, here are decompositions:

19 + 981713 = 981732
29 + 981703 = 981732
41 + 981691 = 981732
79 + 981653 = 981732
109 + 981623 = 981732
131 + 981601 = 981732
163 + 981569 = 981732
239 + 981493 = 981732

Showing the first eight; more decompositions exist.
