Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588592, here are decompositions:

31 + 31588561 = 31588592
109 + 31588483 = 31588592
151 + 31588441 = 31588592
193 + 31588399 = 31588592
223 + 31588369 = 31588592
241 + 31588351 = 31588592
271 + 31588321 = 31588592
421 + 31588171 = 31588592

Showing the first eight; more decompositions exist.
