Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981744, here are decompositions:

13 + 981731 = 981744
31 + 981713 = 981744
37 + 981707 = 981744
41 + 981703 = 981744
47 + 981697 = 981744
53 + 981691 = 981744
61 + 981683 = 981744
107 + 981637 = 981744

Showing the first eight; more decompositions exist.
