Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539598, here are decompositions:

5 + 31539593 = 31539598
11 + 31539587 = 31539598
29 + 31539569 = 31539598
131 + 31539467 = 31539598
197 + 31539401 = 31539598
269 + 31539329 = 31539598
509 + 31539089 = 31539598
647 + 31538951 = 31539598

Showing the first eight; more decompositions exist.
