Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593152, here are decompositions:

43 + 31593109 = 31593152
181 + 31592971 = 31593152
193 + 31592959 = 31593152
229 + 31592923 = 31593152
373 + 31592779 = 31593152
379 + 31592773 = 31593152
601 + 31592551 = 31593152
991 + 31592161 = 31593152

Showing the first eight; more decompositions exist.
