Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105226, here are decompositions:

53 + 105173 = 105226
59 + 105167 = 105226
83 + 105143 = 105226
89 + 105137 = 105226
227 + 104999 = 105226
239 + 104987 = 105226
293 + 104933 = 105226
347 + 104879 = 105226

Showing the first eight; more decompositions exist.
