Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537234, here are decompositions:

5 + 31537229 = 31537234
11 + 31537223 = 31537234
83 + 31537151 = 31537234
101 + 31537133 = 31537234
107 + 31537127 = 31537234
137 + 31537097 = 31537234
191 + 31537043 = 31537234
233 + 31537001 = 31537234

Showing the first eight; more decompositions exist.
