Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971490, here are decompositions:

7 + 971483 = 971490
11 + 971479 = 971490
17 + 971473 = 971490
61 + 971429 = 971490
71 + 971419 = 971490
89 + 971401 = 971490
101 + 971389 = 971490
103 + 971387 = 971490

Showing the first eight; more decompositions exist.
