Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66144, here are decompositions:
- 7 + 66137 = 66144
- 37 + 66107 = 66144
- 41 + 66103 = 66144
- 61 + 66083 = 66144
- 73 + 66071 = 66144
- 97 + 66047 = 66144
- 103 + 66041 = 66144
- 107 + 66037 = 66144
Showing the first eight; more decompositions exist.
