Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105402, here are decompositions:

5 + 105397 = 105402
13 + 105389 = 105402
23 + 105379 = 105402
29 + 105373 = 105402
41 + 105361 = 105402
43 + 105359 = 105402
61 + 105341 = 105402
71 + 105331 = 105402

Showing the first eight; more decompositions exist.
