Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16742, here are decompositions:

13 + 16729 = 16742
43 + 16699 = 16742
109 + 16633 = 16742
139 + 16603 = 16742
181 + 16561 = 16742
223 + 16519 = 16742
331 + 16411 = 16742
373 + 16369 = 16742

Showing the first eight; more decompositions exist.
