Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971478, here are decompositions:

5 + 971473 = 971478
37 + 971441 = 971478
59 + 971419 = 971478
89 + 971389 = 971478
97 + 971381 = 971478
107 + 971371 = 971478
139 + 971339 = 971478
197 + 971281 = 971478

Showing the first eight; more decompositions exist.
