Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593234, here are decompositions:

37 + 31593197 = 31593234
41 + 31593193 = 31593234
61 + 31593173 = 31593234
137 + 31593097 = 31593234
223 + 31593011 = 31593234
241 + 31592993 = 31593234
251 + 31592983 = 31593234
263 + 31592971 = 31593234

Showing the first eight; more decompositions exist.
