Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539594, here are decompositions:

7 + 31539587 = 31539594
11 + 31539583 = 31539594
71 + 31539523 = 31539594
127 + 31539467 = 31539594
173 + 31539421 = 31539594
181 + 31539413 = 31539594
193 + 31539401 = 31539594
227 + 31539367 = 31539594

Showing the first eight; more decompositions exist.
