Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593534, here are decompositions:

17 + 31593517 = 31593534
23 + 31593511 = 31593534
31 + 31593503 = 31593534
43 + 31593491 = 31593534
73 + 31593461 = 31593534
97 + 31593437 = 31593534
157 + 31593377 = 31593534
191 + 31593343 = 31593534

Showing the first eight; more decompositions exist.
