Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534884, here are decompositions:

5 + 31534879 = 31534884
11 + 31534873 = 31534884
13 + 31534871 = 31534884
53 + 31534831 = 31534884
83 + 31534801 = 31534884
97 + 31534787 = 31534884
127 + 31534757 = 31534884
131 + 31534753 = 31534884

Showing the first eight; more decompositions exist.
