Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593822, here are decompositions:

59 + 31593763 = 31593822
101 + 31593721 = 31593822
103 + 31593719 = 31593822
179 + 31593643 = 31593822
181 + 31593641 = 31593822
191 + 31593631 = 31593822
193 + 31593629 = 31593822
233 + 31593589 = 31593822

Showing the first eight; more decompositions exist.
