Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82440, here are decompositions:
- 19 + 82421 = 82440
- 47 + 82393 = 82440
- 53 + 82387 = 82440
- 67 + 82373 = 82440
- 79 + 82361 = 82440
- 89 + 82351 = 82440
- 101 + 82339 = 82440
- 139 + 82301 = 82440
Showing the first eight; more decompositions exist.
