Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593814, here are decompositions:

17 + 31593797 = 31593814
47 + 31593767 = 31593814
167 + 31593647 = 31593814
173 + 31593641 = 31593814
251 + 31593563 = 31593814
281 + 31593533 = 31593814
311 + 31593503 = 31593814
353 + 31593461 = 31593814

Showing the first eight; more decompositions exist.
