Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520594, here are decompositions:

13 + 31520581 = 31520594
67 + 31520527 = 31520594
97 + 31520497 = 31520594
103 + 31520491 = 31520594
223 + 31520371 = 31520594
241 + 31520353 = 31520594
277 + 31520317 = 31520594
421 + 31520173 = 31520594

Showing the first eight; more decompositions exist.
