Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80442, here are decompositions:

13 + 80429 = 80442
73 + 80369 = 80442
79 + 80363 = 80442
101 + 80341 = 80442
113 + 80329 = 80442
163 + 80279 = 80442
179 + 80263 = 80442
191 + 80251 = 80442

Showing the first eight; more decompositions exist.
