Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80518, here are decompositions:

5 + 80513 = 80518
29 + 80489 = 80518
47 + 80471 = 80518
71 + 80447 = 80518
89 + 80429 = 80518
131 + 80387 = 80518
149 + 80369 = 80518
239 + 80279 = 80518

Showing the first eight; more decompositions exist.
