Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593456, here are decompositions:

19 + 31593437 = 31593456
67 + 31593389 = 31593456
79 + 31593377 = 31593456
113 + 31593343 = 31593456
149 + 31593307 = 31593456
157 + 31593299 = 31593456
263 + 31593193 = 31593456
283 + 31593173 = 31593456

Showing the first eight; more decompositions exist.
