Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618112, here are decompositions:

13 + 31618099 = 31618112
109 + 31618003 = 31618112
151 + 31617961 = 31618112
223 + 31617889 = 31618112
241 + 31617871 = 31618112
349 + 31617763 = 31618112
433 + 31617679 = 31618112
439 + 31617673 = 31618112

Showing the first eight; more decompositions exist.
