Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80186, here are decompositions:
- 13 + 80173 = 80186
- 19 + 80167 = 80186
- 37 + 80149 = 80186
- 79 + 80107 = 80186
- 109 + 80077 = 80186
- 199 + 79987 = 80186
- 283 + 79903 = 80186
- 313 + 79873 = 80186
Showing the first eight; more decompositions exist.
