Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80390, here are decompositions:

3 + 80387 = 80390
43 + 80347 = 80390
61 + 80329 = 80390
73 + 80317 = 80390
103 + 80287 = 80390
127 + 80263 = 80390
139 + 80251 = 80390
151 + 80239 = 80390

Showing the first eight; more decompositions exist.
