Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40266, here are decompositions:
- 13 + 40253 = 40266
- 29 + 40237 = 40266
- 53 + 40213 = 40266
- 73 + 40193 = 40266
- 89 + 40177 = 40266
- 97 + 40169 = 40266
- 103 + 40163 = 40266
- 113 + 40153 = 40266
Showing the first eight; more decompositions exist.
