Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971530, here are decompositions:

17 + 971513 = 971530
29 + 971501 = 971530
47 + 971483 = 971530
89 + 971441 = 971530
101 + 971429 = 971530
149 + 971381 = 971530
173 + 971357 = 971530
191 + 971339 = 971530

Showing the first eight; more decompositions exist.
