Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80160, here are decompositions:
- 7 + 80153 = 80160
- 11 + 80149 = 80160
- 13 + 80147 = 80160
- 19 + 80141 = 80160
- 53 + 80107 = 80160
- 83 + 80077 = 80160
- 89 + 80071 = 80160
- 109 + 80051 = 80160
Showing the first eight; more decompositions exist.
