Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548040, here are decompositions:

11 + 31548029 = 31548040
23 + 31548017 = 31548040
47 + 31547993 = 31548040
59 + 31547981 = 31548040
107 + 31547933 = 31548040
179 + 31547861 = 31548040
191 + 31547849 = 31548040
257 + 31547783 = 31548040

Showing the first eight; more decompositions exist.
