Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87116, here are decompositions:

13 + 87103 = 87116
67 + 87049 = 87116
79 + 87037 = 87116
103 + 87013 = 87116
157 + 86959 = 87116
193 + 86923 = 87116
349 + 86767 = 87116
373 + 86743 = 87116

Showing the first eight; more decompositions exist.
