Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593412, here are decompositions:

23 + 31593389 = 31593412
113 + 31593299 = 31593412
239 + 31593173 = 31593412
401 + 31593011 = 31593412
419 + 31592993 = 31593412
491 + 31592921 = 31593412
563 + 31592849 = 31593412
569 + 31592843 = 31593412

Showing the first eight; more decompositions exist.
