Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539548, here are decompositions:

109 + 31539439 = 31539548
127 + 31539421 = 31539548
181 + 31539367 = 31539548
199 + 31539349 = 31539548
211 + 31539337 = 31539548
277 + 31539271 = 31539548
307 + 31539241 = 31539548
487 + 31539061 = 31539548

Showing the first eight; more decompositions exist.
