Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593108, here are decompositions:

11 + 31593097 = 31593108
61 + 31593047 = 31593108
97 + 31593011 = 31593108
137 + 31592971 = 31593108
149 + 31592959 = 31593108
311 + 31592797 = 31593108
347 + 31592761 = 31593108
431 + 31592677 = 31593108

Showing the first eight; more decompositions exist.
