Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981724, here are decompositions:

11 + 981713 = 981724
17 + 981707 = 981724
41 + 981683 = 981724
71 + 981653 = 981724
101 + 981623 = 981724
137 + 981587 = 981724
197 + 981527 = 981724
251 + 981473 = 981724

Showing the first eight; more decompositions exist.
