Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80512, here are decompositions:

23 + 80489 = 80512
41 + 80471 = 80512
83 + 80429 = 80512
149 + 80363 = 80512
233 + 80279 = 80512
239 + 80273 = 80512
281 + 80231 = 80512
359 + 80153 = 80512

Showing the first eight; more decompositions exist.
