Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539108, here are decompositions:

19 + 31539089 = 31539108
47 + 31539061 = 31539108
61 + 31539047 = 31539108
101 + 31539007 = 31539108
157 + 31538951 = 31539108
281 + 31538827 = 31539108
379 + 31538729 = 31539108
389 + 31538719 = 31539108

Showing the first eight; more decompositions exist.
