Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593854, here are decompositions:

67 + 31593787 = 31593854
151 + 31593703 = 31593854
211 + 31593643 = 31593854
223 + 31593631 = 31593854
241 + 31593613 = 31593854
283 + 31593571 = 31593854
337 + 31593517 = 31593854
463 + 31593391 = 31593854

Showing the first eight; more decompositions exist.
