Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534314, here are decompositions:

13 + 31534301 = 31534314
17 + 31534297 = 31534314
43 + 31534271 = 31534314
67 + 31534247 = 31534314
73 + 31534241 = 31534314
83 + 31534231 = 31534314
127 + 31534187 = 31534314
131 + 31534183 = 31534314

Showing the first eight; more decompositions exist.
