Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80478, here are decompositions:

5 + 80473 = 80478
7 + 80471 = 80478
29 + 80449 = 80478
31 + 80447 = 80478
71 + 80407 = 80478
109 + 80369 = 80478
131 + 80347 = 80478
137 + 80341 = 80478

Showing the first eight; more decompositions exist.
