Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548822, here are decompositions:

5 + 31548817 = 31548822
59 + 31548763 = 31548822
73 + 31548749 = 31548822
79 + 31548743 = 31548822
83 + 31548739 = 31548822
89 + 31548733 = 31548822
163 + 31548659 = 31548822
181 + 31548641 = 31548822

Showing the first eight; more decompositions exist.
