Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618046, here are decompositions:

3 + 31618043 = 31618046
43 + 31618003 = 31618046
79 + 31617967 = 31618046
157 + 31617889 = 31618046
193 + 31617853 = 31618046
283 + 31617763 = 31618046
349 + 31617697 = 31618046
367 + 31617679 = 31618046

Showing the first eight; more decompositions exist.
