Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618006, here are decompositions:

3 + 31618003 = 31618006
5 + 31618001 = 31618006
47 + 31617959 = 31618006
53 + 31617953 = 31618006
107 + 31617899 = 31618006
179 + 31617827 = 31618006
293 + 31617713 = 31618006
317 + 31617689 = 31618006

Showing the first eight; more decompositions exist.
