Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80212, here are decompositions:
- 3 + 80209 = 80212
- 5 + 80207 = 80212
- 59 + 80153 = 80212
- 71 + 80141 = 80212
- 101 + 80111 = 80212
- 173 + 80039 = 80212
- 191 + 80021 = 80212
- 233 + 79979 = 80212
Showing the first eight; more decompositions exist.
