Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87152, here are decompositions:

3 + 87149 = 87152
19 + 87133 = 87152
31 + 87121 = 87152
103 + 87049 = 87152
139 + 87013 = 87152
193 + 86959 = 87152
223 + 86929 = 87152
229 + 86923 = 87152

Showing the first eight; more decompositions exist.
