Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105338, here are decompositions:

7 + 105331 = 105338
19 + 105319 = 105338
61 + 105277 = 105338
109 + 105229 = 105338
127 + 105211 = 105338
139 + 105199 = 105338
241 + 105097 = 105338
307 + 105031 = 105338

Showing the first eight; more decompositions exist.
