Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971680, here are decompositions:

29 + 971651 = 971680
41 + 971639 = 971680
89 + 971591 = 971680
131 + 971549 = 971680
167 + 971513 = 971680
179 + 971501 = 971680
197 + 971483 = 971680
239 + 971441 = 971680

Showing the first eight; more decompositions exist.
