Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81114, here are decompositions:
- 13 + 81101 = 81114
- 17 + 81097 = 81114
- 31 + 81083 = 81114
- 37 + 81077 = 81114
- 43 + 81071 = 81114
- 67 + 81047 = 81114
- 71 + 81043 = 81114
- 73 + 81041 = 81114
Showing the first eight; more decompositions exist.
