Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594560, here are decompositions:

7 + 31594553 = 31594560
13 + 31594547 = 31594560
59 + 31594501 = 31594560
71 + 31594489 = 31594560
97 + 31594463 = 31594560
131 + 31594429 = 31594560
139 + 31594421 = 31594560
167 + 31594393 = 31594560

Showing the first eight; more decompositions exist.
