Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618084, here are decompositions:

23 + 31618061 = 31618084
41 + 31618043 = 31618084
83 + 31618001 = 31618084
131 + 31617953 = 31618084
257 + 31617827 = 31618084
521 + 31617563 = 31618084
587 + 31617497 = 31618084
653 + 31617431 = 31618084

Showing the first eight; more decompositions exist.
