Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82154, here are decompositions:
- 13 + 82141 = 82154
- 103 + 82051 = 82154
- 151 + 82003 = 82154
- 181 + 81973 = 82154
- 211 + 81943 = 82154
- 223 + 81931 = 82154
- 271 + 81883 = 82154
- 307 + 81847 = 82154
Showing the first eight; more decompositions exist.
