Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596358, here are decompositions:

41 + 31596317 = 31596358
47 + 31596311 = 31596358
149 + 31596209 = 31596358
239 + 31596119 = 31596358
317 + 31596041 = 31596358
389 + 31595969 = 31596358
491 + 31595867 = 31596358
587 + 31595771 = 31596358

Showing the first eight; more decompositions exist.
