Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105392, here are decompositions:

3 + 105389 = 105392
13 + 105379 = 105392
19 + 105373 = 105392
31 + 105361 = 105392
61 + 105331 = 105392
73 + 105319 = 105392
139 + 105253 = 105392
163 + 105229 = 105392

Showing the first eight; more decompositions exist.
