Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548744, here are decompositions:

5 + 31548739 = 31548744
11 + 31548733 = 31548744
47 + 31548697 = 31548744
67 + 31548677 = 31548744
103 + 31548641 = 31548744
131 + 31548613 = 31548744
151 + 31548593 = 31548744
167 + 31548577 = 31548744

Showing the first eight; more decompositions exist.
