Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43542, here are decompositions:

43 + 43499 = 43542
61 + 43481 = 43542
101 + 43441 = 43542
131 + 43411 = 43542
139 + 43403 = 43542
151 + 43391 = 43542
211 + 43331 = 43542
223 + 43319 = 43542

Showing the first eight; more decompositions exist.
