Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82118, here are decompositions:
- 67 + 82051 = 82118
- 79 + 82039 = 82118
- 97 + 82021 = 82118
- 109 + 82009 = 82118
- 151 + 81967 = 82118
- 181 + 81937 = 82118
- 199 + 81919 = 82118
- 271 + 81847 = 82118
Showing the first eight; more decompositions exist.
