Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618552, here are decompositions:

3 + 31618549 = 31618552
5 + 31618547 = 31618552
89 + 31618463 = 31618552
149 + 31618403 = 31618552
191 + 31618361 = 31618552
233 + 31618319 = 31618552
263 + 31618289 = 31618552
353 + 31618199 = 31618552

Showing the first eight; more decompositions exist.
