Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548444, here are decompositions:

13 + 31548431 = 31548444
17 + 31548427 = 31548444
43 + 31548401 = 31548444
101 + 31548343 = 31548444
113 + 31548331 = 31548444
131 + 31548313 = 31548444
157 + 31548287 = 31548444
163 + 31548281 = 31548444

Showing the first eight; more decompositions exist.
