Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105244, here are decompositions:

5 + 105239 = 105244
17 + 105227 = 105244
71 + 105173 = 105244
101 + 105143 = 105244
107 + 105137 = 105244
137 + 105107 = 105244
173 + 105071 = 105244
257 + 104987 = 105244

Showing the first eight; more decompositions exist.
