Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539552, here are decompositions:

29 + 31539523 = 31539552
53 + 31539499 = 31539552
113 + 31539439 = 31539552
131 + 31539421 = 31539552
139 + 31539413 = 31539552
151 + 31539401 = 31539552
199 + 31539353 = 31539552
223 + 31539329 = 31539552

Showing the first eight; more decompositions exist.
