Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523658, here are decompositions:

7 + 31523651 = 31523658
11 + 31523647 = 31523658
59 + 31523599 = 31523658
79 + 31523579 = 31523658
137 + 31523521 = 31523658
181 + 31523477 = 31523658
191 + 31523467 = 31523658
197 + 31523461 = 31523658

Showing the first eight; more decompositions exist.
