Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40290, here are decompositions:
- 7 + 40283 = 40290
- 13 + 40277 = 40290
- 37 + 40253 = 40290
- 53 + 40237 = 40290
- 59 + 40231 = 40290
- 97 + 40193 = 40290
- 101 + 40189 = 40290
- 113 + 40177 = 40290
Showing the first eight; more decompositions exist.
