Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87036, here are decompositions:

23 + 87013 = 87036
43 + 86993 = 87036
67 + 86969 = 87036
97 + 86939 = 87036
107 + 86929 = 87036
109 + 86927 = 87036
113 + 86923 = 87036
167 + 86869 = 87036

Showing the first eight; more decompositions exist.
