Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541712, here are decompositions:

5 + 31541707 = 31541712
19 + 31541693 = 31541712
53 + 31541659 = 31541712
61 + 31541651 = 31541712
79 + 31541633 = 31541712
101 + 31541611 = 31541712
131 + 31541581 = 31541712
149 + 31541563 = 31541712

Showing the first eight; more decompositions exist.
