Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588514, here are decompositions:

31 + 31588483 = 31588514
43 + 31588471 = 31588514
73 + 31588441 = 31588514
157 + 31588357 = 31588514
163 + 31588351 = 31588514
193 + 31588321 = 31588514
211 + 31588303 = 31588514
313 + 31588201 = 31588514

Showing the first eight; more decompositions exist.
