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.
