Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593436, here are decompositions:

47 + 31593389 = 31593436
59 + 31593377 = 31593436
137 + 31593299 = 31593436
239 + 31593197 = 31593436
263 + 31593173 = 31593436
389 + 31593047 = 31593436
443 + 31592993 = 31593436
587 + 31592849 = 31593436

Showing the first eight; more decompositions exist.
