Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39542, here are decompositions:

31 + 39511 = 39542
43 + 39499 = 39542
103 + 39439 = 39542
199 + 39343 = 39542
229 + 39313 = 39542
241 + 39301 = 39542
313 + 39229 = 39542
379 + 39163 = 39542

Showing the first eight; more decompositions exist.
