Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593244, here are decompositions:

47 + 31593197 = 31593244
71 + 31593173 = 31593244
197 + 31593047 = 31593244
233 + 31593011 = 31593244
251 + 31592993 = 31593244
401 + 31592843 = 31593244
593 + 31592651 = 31593244
677 + 31592567 = 31593244

Showing the first eight; more decompositions exist.
