Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539522, here are decompositions:

23 + 31539499 = 31539522
83 + 31539439 = 31539522
101 + 31539421 = 31539522
109 + 31539413 = 31539522
173 + 31539349 = 31539522
191 + 31539331 = 31539522
193 + 31539329 = 31539522
233 + 31539289 = 31539522

Showing the first eight; more decompositions exist.
