Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548100, here are decompositions:

53 + 31548047 = 31548100
71 + 31548029 = 31548100
83 + 31548017 = 31548100
107 + 31547993 = 31548100
167 + 31547933 = 31548100
179 + 31547921 = 31548100
239 + 31547861 = 31548100
251 + 31547849 = 31548100

Showing the first eight; more decompositions exist.
