Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539588, here are decompositions:

5 + 31539583 = 31539588
19 + 31539569 = 31539588
89 + 31539499 = 31539588
149 + 31539439 = 31539588
167 + 31539421 = 31539588
211 + 31539377 = 31539588
239 + 31539349 = 31539588
251 + 31539337 = 31539588

Showing the first eight; more decompositions exist.
