Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81092, here are decompositions:
- 43 + 81049 = 81092
- 61 + 81031 = 81092
- 73 + 81019 = 81092
- 79 + 81013 = 81092
- 103 + 80989 = 81092
- 139 + 80953 = 81092
- 163 + 80929 = 81092
- 181 + 80911 = 81092
Showing the first eight; more decompositions exist.
