Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544026, here are decompositions:

5 + 31544021 = 31544026
29 + 31543997 = 31544026
47 + 31543979 = 31544026
113 + 31543913 = 31544026
149 + 31543877 = 31544026
167 + 31543859 = 31544026
179 + 31543847 = 31544026
197 + 31543829 = 31544026

Showing the first eight; more decompositions exist.
