Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80372, here are decompositions:
- 3 + 80369 = 80372
- 31 + 80341 = 80372
- 43 + 80329 = 80372
- 109 + 80263 = 80372
- 139 + 80233 = 80372
- 151 + 80221 = 80372
- 163 + 80209 = 80372
- 181 + 80191 = 80372
Showing the first eight; more decompositions exist.
