Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593636, here are decompositions:

5 + 31593631 = 31593636
7 + 31593629 = 31593636
23 + 31593613 = 31593636
29 + 31593607 = 31593636
47 + 31593589 = 31593636
73 + 31593563 = 31593636
83 + 31593553 = 31593636
103 + 31593533 = 31593636

Showing the first eight; more decompositions exist.
