Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552026, here are decompositions:

7 + 31552019 = 31552026
29 + 31551997 = 31552026
47 + 31551979 = 31552026
67 + 31551959 = 31552026
89 + 31551937 = 31552026
167 + 31551859 = 31552026
173 + 31551853 = 31552026
199 + 31551827 = 31552026

Showing the first eight; more decompositions exist.
