Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593788, here are decompositions:

67 + 31593721 = 31593788
157 + 31593631 = 31593788
181 + 31593607 = 31593788
199 + 31593589 = 31593788
271 + 31593517 = 31593788
277 + 31593511 = 31593788
397 + 31593391 = 31593788
691 + 31593097 = 31593788

Showing the first eight; more decompositions exist.
