Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105274, here are decompositions:

5 + 105269 = 105274
11 + 105263 = 105274
23 + 105251 = 105274
47 + 105227 = 105274
101 + 105173 = 105274
107 + 105167 = 105274
131 + 105143 = 105274
137 + 105137 = 105274

Showing the first eight; more decompositions exist.
