Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523796, here are decompositions:

43 + 31523753 = 31523796
47 + 31523749 = 31523796
89 + 31523707 = 31523796
127 + 31523669 = 31523796
137 + 31523659 = 31523796
149 + 31523647 = 31523796
163 + 31523633 = 31523796
197 + 31523599 = 31523796

Showing the first eight; more decompositions exist.
