Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971440, here are decompositions:

11 + 971429 = 971440
53 + 971387 = 971440
59 + 971381 = 971440
83 + 971357 = 971440
101 + 971339 = 971440
131 + 971309 = 971440
149 + 971291 = 971440
167 + 971273 = 971440

Showing the first eight; more decompositions exist.
