Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971658, here are decompositions:

5 + 971653 = 971658
7 + 971651 = 971658
19 + 971639 = 971658
67 + 971591 = 971658
89 + 971569 = 971658
97 + 971561 = 971658
109 + 971549 = 971658
137 + 971521 = 971658

Showing the first eight; more decompositions exist.
