Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520576, here are decompositions:

7 + 31520569 = 31520576
67 + 31520509 = 31520576
79 + 31520497 = 31520576
97 + 31520479 = 31520576
223 + 31520353 = 31520576
277 + 31520299 = 31520576
397 + 31520179 = 31520576
457 + 31520119 = 31520576

Showing the first eight; more decompositions exist.
