Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105308, here are decompositions:

31 + 105277 = 105308
79 + 105229 = 105308
97 + 105211 = 105308
109 + 105199 = 105308
211 + 105097 = 105308
271 + 105037 = 105308
277 + 105031 = 105308
337 + 104971 = 105308

Showing the first eight; more decompositions exist.
