Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80066, here are decompositions:
- 67 + 79999 = 80066
- 79 + 79987 = 80066
- 127 + 79939 = 80066
- 163 + 79903 = 80066
- 193 + 79873 = 80066
- 199 + 79867 = 80066
- 223 + 79843 = 80066
- 367 + 79699 = 80066
Showing the first eight; more decompositions exist.
