Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8102, here are decompositions:

13 + 8089 = 8102
43 + 8059 = 8102
109 + 7993 = 8102
139 + 7963 = 8102
151 + 7951 = 8102
223 + 7879 = 8102
229 + 7873 = 8102
313 + 7789 = 8102

Showing the first eight; more decompositions exist.
