Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82980, here are decompositions:
- 17 + 82963 = 82980
- 41 + 82939 = 82980
- 67 + 82913 = 82980
- 89 + 82891 = 82980
- 97 + 82883 = 82980
- 167 + 82813 = 82980
- 181 + 82799 = 82980
- 193 + 82787 = 82980
Showing the first eight; more decompositions exist.
