Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534284, here are decompositions:

13 + 31534271 = 31534284
37 + 31534247 = 31534284
43 + 31534241 = 31534284
53 + 31534231 = 31534284
97 + 31534187 = 31534284
101 + 31534183 = 31534284
163 + 31534121 = 31534284
167 + 31534117 = 31534284

Showing the first eight; more decompositions exist.
