Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620024, here are decompositions:

5 + 31620019 = 31620024
11 + 31620013 = 31620024
31 + 31619993 = 31620024
43 + 31619981 = 31620024
71 + 31619953 = 31620024
113 + 31619911 = 31620024
181 + 31619843 = 31620024
223 + 31619801 = 31620024

Showing the first eight; more decompositions exist.
