Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593924, here are decompositions:

23 + 31593901 = 31593924
127 + 31593797 = 31593924
137 + 31593787 = 31593924
157 + 31593767 = 31593924
277 + 31593647 = 31593924
281 + 31593643 = 31593924
283 + 31593641 = 31593924
293 + 31593631 = 31593924

Showing the first eight; more decompositions exist.
