Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593198, here are decompositions:

5 + 31593193 = 31593198
89 + 31593109 = 31593198
101 + 31593097 = 31593198
151 + 31593047 = 31593198
167 + 31593031 = 31593198
227 + 31592971 = 31593198
239 + 31592959 = 31593198
251 + 31592947 = 31593198

Showing the first eight; more decompositions exist.
