Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539104, here are decompositions:

31 + 31539073 = 31539104
43 + 31539061 = 31539104
61 + 31539043 = 31539104
97 + 31539007 = 31539104
277 + 31538827 = 31539104
433 + 31538671 = 31539104
463 + 31538641 = 31539104
523 + 31538581 = 31539104

Showing the first eight; more decompositions exist.
