Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593894, here are decompositions:

61 + 31593833 = 31593894
97 + 31593797 = 31593894
107 + 31593787 = 31593894
127 + 31593767 = 31593894
131 + 31593763 = 31593894
173 + 31593721 = 31593894
191 + 31593703 = 31593894
251 + 31593643 = 31593894

Showing the first eight; more decompositions exist.
