Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548126, here are decompositions:

17 + 31548109 = 31548126
23 + 31548103 = 31548126
47 + 31548079 = 31548126
79 + 31548047 = 31548126
97 + 31548029 = 31548126
109 + 31548017 = 31548126
167 + 31547959 = 31548126
173 + 31547953 = 31548126

Showing the first eight; more decompositions exist.
