Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87102, here are decompositions:

19 + 87083 = 87102
31 + 87071 = 87102
53 + 87049 = 87102
61 + 87041 = 87102
89 + 87013 = 87102
109 + 86993 = 87102
151 + 86951 = 87102
163 + 86939 = 87102

Showing the first eight; more decompositions exist.
