Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80210, here are decompositions:

3 + 80207 = 80210
19 + 80191 = 80210
37 + 80173 = 80210
43 + 80167 = 80210
61 + 80149 = 80210
103 + 80107 = 80210
139 + 80071 = 80210
211 + 79999 = 80210

Showing the first eight; more decompositions exist.
