Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971428, here are decompositions:

41 + 971387 = 971428
47 + 971381 = 971428
71 + 971357 = 971428
89 + 971339 = 971428
137 + 971291 = 971428
149 + 971279 = 971428
191 + 971237 = 971428
251 + 971177 = 971428

Showing the first eight; more decompositions exist.
