Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12980, here are decompositions:
- 7 + 12973 = 12980
- 13 + 12967 = 12980
- 61 + 12919 = 12980
- 73 + 12907 = 12980
- 127 + 12853 = 12980
- 139 + 12841 = 12980
- 151 + 12829 = 12980
- 157 + 12823 = 12980
Showing the first eight; more decompositions exist.
