Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102242, here are decompositions:

13 + 102229 = 102242
43 + 102199 = 102242
61 + 102181 = 102242
103 + 102139 = 102242
139 + 102103 = 102242
163 + 102079 = 102242
181 + 102061 = 102242
199 + 102043 = 102242

Showing the first eight; more decompositions exist.
