Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40394, here are decompositions:
- 7 + 40387 = 40394
- 37 + 40357 = 40394
- 43 + 40351 = 40394
- 157 + 40237 = 40394
- 163 + 40231 = 40394
- 181 + 40213 = 40394
- 241 + 40153 = 40394
- 271 + 40123 = 40394
Showing the first eight; more decompositions exist.
