Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87918, here are decompositions:

7 + 87911 = 87918
31 + 87887 = 87918
37 + 87881 = 87918
41 + 87877 = 87918
107 + 87811 = 87918
151 + 87767 = 87918
167 + 87751 = 87918
179 + 87739 = 87918

Showing the first eight; more decompositions exist.
