Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80542, here are decompositions:

5 + 80537 = 80542
29 + 80513 = 80542
53 + 80489 = 80542
71 + 80471 = 80542
113 + 80429 = 80542
173 + 80369 = 80542
179 + 80363 = 80542
233 + 80309 = 80542

Showing the first eight; more decompositions exist.
