Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105422, here are decompositions:

43 + 105379 = 105422
61 + 105361 = 105422
103 + 105319 = 105422
193 + 105229 = 105422
211 + 105211 = 105422
223 + 105199 = 105422
463 + 104959 = 105422
571 + 104851 = 105422

Showing the first eight; more decompositions exist.
