Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981716, here are decompositions:

3 + 981713 = 981716
13 + 981703 = 981716
19 + 981697 = 981716
79 + 981637 = 981716
139 + 981577 = 981716
193 + 981523 = 981716
199 + 981517 = 981716
223 + 981493 = 981716

Showing the first eight; more decompositions exist.
