Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105470, here are decompositions:

3 + 105467 = 105470
73 + 105397 = 105470
97 + 105373 = 105470
103 + 105367 = 105470
109 + 105361 = 105470
139 + 105331 = 105470
151 + 105319 = 105470
193 + 105277 = 105470

Showing the first eight; more decompositions exist.
