Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87836, here are decompositions:

3 + 87833 = 87836
43 + 87793 = 87836
97 + 87739 = 87836
139 + 87697 = 87836
157 + 87679 = 87836
193 + 87643 = 87836
223 + 87613 = 87836
277 + 87559 = 87836

Showing the first eight; more decompositions exist.
