Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548836, here are decompositions:

13 + 31548823 = 31548836
19 + 31548817 = 31548836
73 + 31548763 = 31548836
79 + 31548757 = 31548836
97 + 31548739 = 31548836
103 + 31548733 = 31548836
139 + 31548697 = 31548836
223 + 31548613 = 31548836

Showing the first eight; more decompositions exist.
