Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618952, here are decompositions:

3 + 31618949 = 31618952
61 + 31618891 = 31618952
73 + 31618879 = 31618952
103 + 31618849 = 31618952
181 + 31618771 = 31618952
199 + 31618753 = 31618952
241 + 31618711 = 31618952
271 + 31618681 = 31618952

Showing the first eight; more decompositions exist.
