Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593848, here are decompositions:

61 + 31593787 = 31593848
127 + 31593721 = 31593848
241 + 31593607 = 31593848
277 + 31593571 = 31593848
331 + 31593517 = 31593848
337 + 31593511 = 31593848
457 + 31593391 = 31593848
541 + 31593307 = 31593848

Showing the first eight; more decompositions exist.
