Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40370, here are decompositions:
- 13 + 40357 = 40370
- 19 + 40351 = 40370
- 139 + 40231 = 40370
- 157 + 40213 = 40370
- 181 + 40189 = 40370
- 193 + 40177 = 40370
- 241 + 40129 = 40370
- 271 + 40099 = 40370
Showing the first eight; more decompositions exist.
