Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80840, here are decompositions:
- 7 + 80833 = 80840
- 31 + 80809 = 80840
- 37 + 80803 = 80840
- 61 + 80779 = 80840
- 79 + 80761 = 80840
- 103 + 80737 = 80840
- 127 + 80713 = 80840
- 139 + 80701 = 80840
Showing the first eight; more decompositions exist.
