Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539608, here are decompositions:

109 + 31539499 = 31539608
241 + 31539367 = 31539608
271 + 31539337 = 31539608
277 + 31539331 = 31539608
337 + 31539271 = 31539608
367 + 31539241 = 31539608
379 + 31539229 = 31539608
547 + 31539061 = 31539608

Showing the first eight; more decompositions exist.
