Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105342, here are decompositions:

5 + 105337 = 105342
11 + 105331 = 105342
19 + 105323 = 105342
23 + 105319 = 105342
73 + 105269 = 105342
79 + 105263 = 105342
89 + 105253 = 105342
103 + 105239 = 105342

Showing the first eight; more decompositions exist.
