Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66154, here are decompositions:
- 17 + 66137 = 66154
- 47 + 66107 = 66154
- 71 + 66083 = 66154
- 83 + 66071 = 66154
- 107 + 66047 = 66154
- 113 + 66041 = 66154
- 173 + 65981 = 66154
- 191 + 65963 = 66154
Showing the first eight; more decompositions exist.
