Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102248, here are decompositions:

7 + 102241 = 102248
19 + 102229 = 102248
31 + 102217 = 102248
67 + 102181 = 102248
109 + 102139 = 102248
127 + 102121 = 102248
229 + 102019 = 102248
271 + 101977 = 102248

Showing the first eight; more decompositions exist.
