Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87946, here are decompositions:

3 + 87943 = 87946
29 + 87917 = 87946
59 + 87887 = 87946
113 + 87833 = 87946
149 + 87797 = 87946
179 + 87767 = 87946
227 + 87719 = 87946
263 + 87683 = 87946

Showing the first eight; more decompositions exist.
