Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80318, here are decompositions:
- 31 + 80287 = 80318
- 67 + 80251 = 80318
- 79 + 80239 = 80318
- 97 + 80221 = 80318
- 109 + 80209 = 80318
- 127 + 80191 = 80318
- 151 + 80167 = 80318
- 211 + 80107 = 80318
Showing the first eight; more decompositions exist.
