Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81214, here are decompositions:
- 11 + 81203 = 81214
- 17 + 81197 = 81214
- 41 + 81173 = 81214
- 83 + 81131 = 81214
- 113 + 81101 = 81214
- 131 + 81083 = 81214
- 137 + 81077 = 81214
- 167 + 81047 = 81214
Showing the first eight; more decompositions exist.
