Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593186, here are decompositions:

13 + 31593173 = 31593186
89 + 31593097 = 31593186
139 + 31593047 = 31593186
193 + 31592993 = 31593186
227 + 31592959 = 31593186
239 + 31592947 = 31593186
263 + 31592923 = 31593186
337 + 31592849 = 31593186

Showing the first eight; more decompositions exist.
