Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80822, here are decompositions:
- 3 + 80819 = 80822
- 13 + 80809 = 80822
- 19 + 80803 = 80822
- 43 + 80779 = 80822
- 61 + 80761 = 80822
- 73 + 80749 = 80822
- 109 + 80713 = 80822
- 139 + 80683 = 80822
Showing the first eight; more decompositions exist.
