Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618108, here are decompositions:

47 + 31618061 = 31618108
59 + 31618049 = 31618108
107 + 31618001 = 31618108
149 + 31617959 = 31618108
167 + 31617941 = 31618108
281 + 31617827 = 31618108
311 + 31617797 = 31618108
419 + 31617689 = 31618108

Showing the first eight; more decompositions exist.
