Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105542, here are decompositions:

13 + 105529 = 105542
43 + 105499 = 105542
163 + 105379 = 105542
181 + 105361 = 105542
211 + 105331 = 105542
223 + 105319 = 105542
313 + 105229 = 105542
331 + 105211 = 105542

Showing the first eight; more decompositions exist.
