Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593632, here are decompositions:

3 + 31593629 = 31593632
19 + 31593613 = 31593632
43 + 31593589 = 31593632
61 + 31593571 = 31593632
79 + 31593553 = 31593632
241 + 31593391 = 31593632
379 + 31593253 = 31593632
439 + 31593193 = 31593632

Showing the first eight; more decompositions exist.
