Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971816, here are decompositions:

103 + 971713 = 971816
163 + 971653 = 971816
337 + 971479 = 971816
397 + 971419 = 971816
463 + 971353 = 971816
619 + 971197 = 971816
673 + 971143 = 971816
739 + 971077 = 971816

Showing the first eight; more decompositions exist.
