Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588362, here are decompositions:

5 + 31588357 = 31588362
11 + 31588351 = 31588362
31 + 31588331 = 31588362
41 + 31588321 = 31588362
59 + 31588303 = 31588362
109 + 31588253 = 31588362
163 + 31588199 = 31588362
191 + 31588171 = 31588362

Showing the first eight; more decompositions exist.
