Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105432, here are decompositions:

31 + 105401 = 105432
43 + 105389 = 105432
53 + 105379 = 105432
59 + 105373 = 105432
71 + 105361 = 105432
73 + 105359 = 105432
101 + 105331 = 105432
109 + 105323 = 105432

Showing the first eight; more decompositions exist.
