Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593672, here are decompositions:

29 + 31593643 = 31593672
31 + 31593641 = 31593672
41 + 31593631 = 31593672
43 + 31593629 = 31593672
59 + 31593613 = 31593672
83 + 31593589 = 31593672
101 + 31593571 = 31593672
109 + 31593563 = 31593672

Showing the first eight; more decompositions exist.
