Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539332, here are decompositions:

3 + 31539329 = 31539332
43 + 31539289 = 31539332
61 + 31539271 = 31539332
103 + 31539229 = 31539332
271 + 31539061 = 31539332
613 + 31538719 = 31539332
619 + 31538713 = 31539332
661 + 31538671 = 31539332

Showing the first eight; more decompositions exist.
