Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105254, here are decompositions:

3 + 105251 = 105254
43 + 105211 = 105254
157 + 105097 = 105254
223 + 105031 = 105254
283 + 104971 = 105254
307 + 104947 = 105254
337 + 104917 = 105254
547 + 104707 = 105254

Showing the first eight; more decompositions exist.
