Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971578, here are decompositions:

17 + 971561 = 971578
29 + 971549 = 971578
137 + 971441 = 971578
149 + 971429 = 971578
191 + 971387 = 971578
197 + 971381 = 971578
239 + 971339 = 971578
269 + 971309 = 971578

Showing the first eight; more decompositions exist.
