Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16520, here are decompositions:

43 + 16477 = 16520
67 + 16453 = 16520
73 + 16447 = 16520
103 + 16417 = 16520
109 + 16411 = 16520
139 + 16381 = 16520
151 + 16369 = 16520
157 + 16363 = 16520

Showing the first eight; more decompositions exist.
