Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523168, here are decompositions:

7 + 31523161 = 31523168
37 + 31523131 = 31523168
181 + 31522987 = 31523168
421 + 31522747 = 31523168
499 + 31522669 = 31523168
571 + 31522597 = 31523168
577 + 31522591 = 31523168
619 + 31522549 = 31523168

Showing the first eight; more decompositions exist.
