Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80180, here are decompositions:
- 3 + 80177 = 80180
- 7 + 80173 = 80180
- 13 + 80167 = 80180
- 31 + 80149 = 80180
- 73 + 80107 = 80180
- 103 + 80077 = 80180
- 109 + 80071 = 80180
- 181 + 79999 = 80180
Showing the first eight; more decompositions exist.
