Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618964, here are decompositions:

67 + 31618897 = 31618964
73 + 31618891 = 31618964
193 + 31618771 = 31618964
211 + 31618753 = 31618964
271 + 31618693 = 31618964
283 + 31618681 = 31618964
331 + 31618633 = 31618964
367 + 31618597 = 31618964

Showing the first eight; more decompositions exist.
