Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105224, here are decompositions:

13 + 105211 = 105224
127 + 105097 = 105224
193 + 105031 = 105224
271 + 104953 = 105224
277 + 104947 = 105224
307 + 104917 = 105224
313 + 104911 = 105224
373 + 104851 = 105224

Showing the first eight; more decompositions exist.
