Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590348, here are decompositions:

5 + 31590343 = 31590348
71 + 31590277 = 31590348
79 + 31590269 = 31590348
107 + 31590241 = 31590348
137 + 31590211 = 31590348
199 + 31590149 = 31590348
211 + 31590137 = 31590348
227 + 31590121 = 31590348

Showing the first eight; more decompositions exist.
