Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523670, here are decompositions:

11 + 31523659 = 31523670
19 + 31523651 = 31523670
23 + 31523647 = 31523670
37 + 31523633 = 31523670
71 + 31523599 = 31523670
131 + 31523539 = 31523670
149 + 31523521 = 31523670
193 + 31523477 = 31523670

Showing the first eight; more decompositions exist.
