Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80136, here are decompositions:
- 29 + 80107 = 80136
- 59 + 80077 = 80136
- 97 + 80039 = 80136
- 137 + 79999 = 80136
- 139 + 79997 = 80136
- 149 + 79987 = 80136
- 157 + 79979 = 80136
- 163 + 79973 = 80136
Showing the first eight; more decompositions exist.
