Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593884, here are decompositions:

97 + 31593787 = 31593884
163 + 31593721 = 31593884
181 + 31593703 = 31593884
241 + 31593643 = 31593884
271 + 31593613 = 31593884
277 + 31593607 = 31593884
313 + 31593571 = 31593884
331 + 31593553 = 31593884

Showing the first eight; more decompositions exist.
