Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80662, here are decompositions:

5 + 80657 = 80662
11 + 80651 = 80662
41 + 80621 = 80662
59 + 80603 = 80662
149 + 80513 = 80662
173 + 80489 = 80662
191 + 80471 = 80662
233 + 80429 = 80662

Showing the first eight; more decompositions exist.
