Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77644, here are decompositions:
- 3 + 77641 = 77644
- 23 + 77621 = 77644
- 53 + 77591 = 77644
- 71 + 77573 = 77644
- 101 + 77543 = 77644
- 131 + 77513 = 77644
- 167 + 77477 = 77644
- 173 + 77471 = 77644
Showing the first eight; more decompositions exist.
