Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626024, here are decompositions:

5 + 31626019 = 31626024
13 + 31626011 = 31626024
37 + 31625987 = 31626024
43 + 31625981 = 31626024
61 + 31625963 = 31626024
71 + 31625953 = 31626024
107 + 31625917 = 31626024
113 + 31625911 = 31626024

Showing the first eight; more decompositions exist.
