Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593040, here are decompositions:

29 + 31593011 = 31593040
47 + 31592993 = 31593040
191 + 31592849 = 31593040
197 + 31592843 = 31593040
293 + 31592747 = 31593040
389 + 31592651 = 31593040
419 + 31592621 = 31593040
509 + 31592531 = 31593040

Showing the first eight; more decompositions exist.
