Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588464, here are decompositions:

23 + 31588441 = 31588464
97 + 31588367 = 31588464
107 + 31588357 = 31588464
113 + 31588351 = 31588464
151 + 31588313 = 31588464
157 + 31588307 = 31588464
197 + 31588267 = 31588464
211 + 31588253 = 31588464

Showing the first eight; more decompositions exist.
