Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16442, here are decompositions:

31 + 16411 = 16442
61 + 16381 = 16442
73 + 16369 = 16442
79 + 16363 = 16442
103 + 16339 = 16442
109 + 16333 = 16442
193 + 16249 = 16442
211 + 16231 = 16442

Showing the first eight; more decompositions exist.
