Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590564, here are decompositions:

7 + 31590557 = 31590564
13 + 31590551 = 31590564
97 + 31590467 = 31590564
101 + 31590463 = 31590564
113 + 31590451 = 31590564
151 + 31590413 = 31590564
163 + 31590401 = 31590564
167 + 31590397 = 31590564

Showing the first eight; more decompositions exist.
