Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87026, here are decompositions:

13 + 87013 = 87026
67 + 86959 = 87026
97 + 86929 = 87026
103 + 86923 = 87026
157 + 86869 = 87026
283 + 86743 = 87026
307 + 86719 = 87026
337 + 86689 = 87026

Showing the first eight; more decompositions exist.
