Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87816, here are decompositions:

5 + 87811 = 87816
13 + 87803 = 87816
19 + 87797 = 87816
23 + 87793 = 87816
73 + 87743 = 87816
97 + 87719 = 87816
137 + 87679 = 87816
167 + 87649 = 87816

Showing the first eight; more decompositions exist.
