Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20774, here are decompositions:
- 3 + 20771 = 20774
- 31 + 20743 = 20774
- 43 + 20731 = 20774
- 67 + 20707 = 20774
- 163 + 20611 = 20774
- 181 + 20593 = 20774
- 211 + 20563 = 20774
- 223 + 20551 = 20774
Showing the first eight; more decompositions exist.
