Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971518, here are decompositions:

5 + 971513 = 971518
17 + 971501 = 971518
89 + 971429 = 971518
131 + 971387 = 971518
137 + 971381 = 971518
179 + 971339 = 971518
227 + 971291 = 971518
239 + 971279 = 971518

Showing the first eight; more decompositions exist.
