Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71816, here are decompositions:

7 + 71809 = 71816
97 + 71719 = 71816
103 + 71713 = 71816
109 + 71707 = 71816
223 + 71593 = 71816
313 + 71503 = 71816
337 + 71479 = 71816
373 + 71443 = 71816

Showing the first eight; more decompositions exist.
