Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66078, here are decompositions:
- 7 + 66071 = 66078
- 11 + 66067 = 66078
- 31 + 66047 = 66078
- 37 + 66041 = 66078
- 41 + 66037 = 66078
- 97 + 65981 = 66078
- 127 + 65951 = 66078
- 149 + 65929 = 66078
Showing the first eight; more decompositions exist.
