Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80918, here are decompositions:

7 + 80911 = 80918
109 + 80809 = 80918
139 + 80779 = 80918
157 + 80761 = 80918
181 + 80737 = 80918
241 + 80677 = 80918
307 + 80611 = 80918
571 + 80347 = 80918

Showing the first eight; more decompositions exist.
