Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80240, here are decompositions:

7 + 80233 = 80240
19 + 80221 = 80240
31 + 80209 = 80240
67 + 80173 = 80240
73 + 80167 = 80240
163 + 80077 = 80240
241 + 79999 = 80240
337 + 79903 = 80240

Showing the first eight; more decompositions exist.
