Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593998, here are decompositions:

61 + 31593937 = 31593998
67 + 31593931 = 31593998
97 + 31593901 = 31593998
211 + 31593787 = 31593998
277 + 31593721 = 31593998
367 + 31593631 = 31593998
409 + 31593589 = 31593998
487 + 31593511 = 31593998

Showing the first eight; more decompositions exist.
