Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571592, here are decompositions:

23 + 31571569 = 31571592
139 + 31571453 = 31571592
179 + 31571413 = 31571592
193 + 31571399 = 31571592
211 + 31571381 = 31571592
373 + 31571219 = 31571592
379 + 31571213 = 31571592
401 + 31571191 = 31571592

Showing the first eight; more decompositions exist.
