Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80450, here are decompositions:
- 3 + 80447 = 80450
- 43 + 80407 = 80450
- 103 + 80347 = 80450
- 109 + 80341 = 80450
- 163 + 80287 = 80450
- 199 + 80251 = 80450
- 211 + 80239 = 80450
- 229 + 80221 = 80450
Showing the first eight; more decompositions exist.
