Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539050, here are decompositions:

3 + 31539047 = 31539050
7 + 31539043 = 31539050
43 + 31539007 = 31539050
163 + 31538887 = 31539050
223 + 31538827 = 31539050
271 + 31538779 = 31539050
307 + 31538743 = 31539050
331 + 31538719 = 31539050

Showing the first eight; more decompositions exist.
