Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40180, here are decompositions:
- 3 + 40177 = 40180
- 11 + 40169 = 40180
- 17 + 40163 = 40180
- 29 + 40151 = 40180
- 53 + 40127 = 40180
- 149 + 40031 = 40180
- 167 + 40013 = 40180
- 191 + 39989 = 40180
Showing the first eight; more decompositions exist.
