Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51644, here are decompositions:
- 7 + 51637 = 51644
- 13 + 51631 = 51644
- 31 + 51613 = 51644
- 37 + 51607 = 51644
- 67 + 51577 = 51644
- 127 + 51517 = 51644
- 157 + 51487 = 51644
- 163 + 51481 = 51644
Showing the first eight; more decompositions exist.
