Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585462, here are decompositions:

3 + 31585459 = 31585462
11 + 31585451 = 31585462
101 + 31585361 = 31585462
131 + 31585331 = 31585462
149 + 31585313 = 31585462
173 + 31585289 = 31585462
191 + 31585271 = 31585462
263 + 31585199 = 31585462

Showing the first eight; more decompositions exist.
