Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51568, here are decompositions:
- 5 + 51563 = 51568
- 17 + 51551 = 51568
- 29 + 51539 = 51568
- 47 + 51521 = 51568
- 89 + 51479 = 51568
- 107 + 51461 = 51568
- 131 + 51437 = 51568
- 137 + 51431 = 51568
Showing the first eight; more decompositions exist.
