Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618052, here are decompositions:

3 + 31618049 = 31618052
163 + 31617889 = 31618052
181 + 31617871 = 31618052
199 + 31617853 = 31618052
241 + 31617811 = 31618052
373 + 31617679 = 31618052
379 + 31617673 = 31618052
421 + 31617631 = 31618052

Showing the first eight; more decompositions exist.
