Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594576, here are decompositions:

3 + 31594573 = 31594576
23 + 31594553 = 31594576
29 + 31594547 = 31594576
113 + 31594463 = 31594576
383 + 31594193 = 31594576
443 + 31594133 = 31594576
479 + 31594097 = 31594576
593 + 31593983 = 31594576

Showing the first eight; more decompositions exist.
