Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105230, here are decompositions:

3 + 105227 = 105230
19 + 105211 = 105230
31 + 105199 = 105230
193 + 105037 = 105230
199 + 105031 = 105230
211 + 105019 = 105230
271 + 104959 = 105230
277 + 104953 = 105230

Showing the first eight; more decompositions exist.
