Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40208, here are decompositions:
- 19 + 40189 = 40208
- 31 + 40177 = 40208
- 79 + 40129 = 40208
- 97 + 40111 = 40208
- 109 + 40099 = 40208
- 199 + 40009 = 40208
- 229 + 39979 = 40208
- 271 + 39937 = 40208
Showing the first eight; more decompositions exist.
