Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971620, here are decompositions:

29 + 971591 = 971620
59 + 971561 = 971620
71 + 971549 = 971620
107 + 971513 = 971620
137 + 971483 = 971620
179 + 971441 = 971620
191 + 971429 = 971620
233 + 971387 = 971620

Showing the first eight; more decompositions exist.
