Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16490, here are decompositions:

3 + 16487 = 16490
13 + 16477 = 16490
37 + 16453 = 16490
43 + 16447 = 16490
73 + 16417 = 16490
79 + 16411 = 16490
109 + 16381 = 16490
127 + 16363 = 16490

Showing the first eight; more decompositions exist.
