Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539748, here are decompositions:

11 + 31539737 = 31539748
41 + 31539707 = 31539748
89 + 31539659 = 31539748
179 + 31539569 = 31539748
281 + 31539467 = 31539748
347 + 31539401 = 31539748
419 + 31539329 = 31539748
557 + 31539191 = 31539748

Showing the first eight; more decompositions exist.
