Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105518, here are decompositions:

19 + 105499 = 105518
139 + 105379 = 105518
151 + 105367 = 105518
157 + 105361 = 105518
181 + 105337 = 105518
199 + 105319 = 105518
241 + 105277 = 105518
307 + 105211 = 105518

Showing the first eight; more decompositions exist.
