Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16478, here are decompositions:

31 + 16447 = 16478
61 + 16417 = 16478
67 + 16411 = 16478
97 + 16381 = 16478
109 + 16369 = 16478
139 + 16339 = 16478
211 + 16267 = 16478
229 + 16249 = 16478

Showing the first eight; more decompositions exist.
