Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533954, here are decompositions:

5 + 31533949 = 31533954
31 + 31533923 = 31533954
43 + 31533911 = 31533954
83 + 31533871 = 31533954
107 + 31533847 = 31533954
131 + 31533823 = 31533954
163 + 31533791 = 31533954
181 + 31533773 = 31533954

Showing the first eight; more decompositions exist.
