Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45456, here are decompositions:
- 17 + 45439 = 45456
- 23 + 45433 = 45456
- 29 + 45427 = 45456
- 43 + 45413 = 45456
- 53 + 45403 = 45456
- 67 + 45389 = 45456
- 79 + 45377 = 45456
- 113 + 45343 = 45456
Showing the first eight; more decompositions exist.
