Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593620, here are decompositions:

7 + 31593613 = 31593620
13 + 31593607 = 31593620
31 + 31593589 = 31593620
67 + 31593553 = 31593620
103 + 31593517 = 31593620
109 + 31593511 = 31593620
229 + 31593391 = 31593620
277 + 31593343 = 31593620

Showing the first eight; more decompositions exist.
