Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80220, here are decompositions:
- 11 + 80209 = 80220
- 13 + 80207 = 80220
- 29 + 80191 = 80220
- 43 + 80177 = 80220
- 47 + 80173 = 80220
- 53 + 80167 = 80220
- 67 + 80153 = 80220
- 71 + 80149 = 80220
Showing the first eight; more decompositions exist.
