Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105148, here are decompositions:

5 + 105143 = 105148
11 + 105137 = 105148
41 + 105107 = 105148
149 + 104999 = 105148
257 + 104891 = 105148
269 + 104879 = 105148
317 + 104831 = 105148
347 + 104801 = 105148

Showing the first eight; more decompositions exist.
