Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80864, here are decompositions:
- 31 + 80833 = 80864
- 61 + 80803 = 80864
- 103 + 80761 = 80864
- 127 + 80737 = 80864
- 151 + 80713 = 80864
- 163 + 80701 = 80864
- 181 + 80683 = 80864
- 193 + 80671 = 80864
Showing the first eight; more decompositions exist.
