Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527696, here are decompositions:

7 + 31527689 = 31527696
19 + 31527677 = 31527696
37 + 31527659 = 31527696
113 + 31527583 = 31527696
127 + 31527569 = 31527696
163 + 31527533 = 31527696
173 + 31527523 = 31527696
197 + 31527499 = 31527696

Showing the first eight; more decompositions exist.
