Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548042, here are decompositions:

11 + 31548031 = 31548042
13 + 31548029 = 31548042
61 + 31547981 = 31548042
83 + 31547959 = 31548042
89 + 31547953 = 31548042
109 + 31547933 = 31548042
181 + 31547861 = 31548042
191 + 31547851 = 31548042

Showing the first eight; more decompositions exist.
