Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588392, here are decompositions:

23 + 31588369 = 31588392
41 + 31588351 = 31588392
61 + 31588331 = 31588392
71 + 31588321 = 31588392
79 + 31588313 = 31588392
89 + 31588303 = 31588392
139 + 31588253 = 31588392
191 + 31588201 = 31588392

Showing the first eight; more decompositions exist.
