Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588324, here are decompositions:

3 + 31588321 = 31588324
11 + 31588313 = 31588324
17 + 31588307 = 31588324
71 + 31588253 = 31588324
167 + 31588157 = 31588324
263 + 31588061 = 31588324
401 + 31587923 = 31588324
431 + 31587893 = 31588324

Showing the first eight; more decompositions exist.
