Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105260, here are decompositions:

7 + 105253 = 105260
31 + 105229 = 105260
61 + 105199 = 105260
163 + 105097 = 105260
223 + 105037 = 105260
229 + 105031 = 105260
241 + 105019 = 105260
307 + 104953 = 105260

Showing the first eight; more decompositions exist.
