Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981726, here are decompositions:

13 + 981713 = 981726
19 + 981707 = 981726
23 + 981703 = 981726
29 + 981697 = 981726
43 + 981683 = 981726
73 + 981653 = 981726
89 + 981637 = 981726
103 + 981623 = 981726

Showing the first eight; more decompositions exist.
