Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534384, here are decompositions:

41 + 31534343 = 31534384
83 + 31534301 = 31534384
113 + 31534271 = 31534384
137 + 31534247 = 31534384
197 + 31534187 = 31534384
263 + 31534121 = 31534384
281 + 31534103 = 31534384
311 + 31534073 = 31534384

Showing the first eight; more decompositions exist.
