Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971500, here are decompositions:

17 + 971483 = 971500
59 + 971441 = 971500
71 + 971429 = 971500
113 + 971387 = 971500
191 + 971309 = 971500
227 + 971273 = 971500
263 + 971237 = 971500
293 + 971207 = 971500

Showing the first eight; more decompositions exist.
