Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80980, here are decompositions:
- 17 + 80963 = 80980
- 47 + 80933 = 80980
- 71 + 80909 = 80980
- 83 + 80897 = 80980
- 131 + 80849 = 80980
- 149 + 80831 = 80980
- 191 + 80789 = 80980
- 197 + 80783 = 80980
Showing the first eight; more decompositions exist.
