Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539048, here are decompositions:

5 + 31539043 = 31539048
41 + 31539007 = 31539048
61 + 31538987 = 31539048
97 + 31538951 = 31539048
241 + 31538807 = 31539048
269 + 31538779 = 31539048
337 + 31538711 = 31539048
419 + 31538629 = 31539048

Showing the first eight; more decompositions exist.
