Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688258, here are decompositions:

37 + 8688221 = 8688258
97 + 8688161 = 8688258
101 + 8688157 = 8688258
149 + 8688109 = 8688258
157 + 8688101 = 8688258
181 + 8688077 = 8688258
191 + 8688067 = 8688258
199 + 8688059 = 8688258

Showing the first eight; more decompositions exist.
