Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26210, here are decompositions:

7 + 26203 = 26210
97 + 26113 = 26210
103 + 26107 = 26210
127 + 26083 = 26210
157 + 26053 = 26210
181 + 26029 = 26210
193 + 26017 = 26210
211 + 25999 = 26210

Showing the first eight; more decompositions exist.
