Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80216, here are decompositions:
- 7 + 80209 = 80216
- 43 + 80173 = 80216
- 67 + 80149 = 80216
- 109 + 80107 = 80216
- 139 + 80077 = 80216
- 229 + 79987 = 80216
- 277 + 79939 = 80216
- 313 + 79903 = 80216
Showing the first eight; more decompositions exist.
