Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72568, here are decompositions:
- 17 + 72551 = 72568
- 71 + 72497 = 72568
- 101 + 72467 = 72568
- 107 + 72461 = 72568
- 137 + 72431 = 72568
- 227 + 72341 = 72568
- 281 + 72287 = 72568
- 317 + 72251 = 72568
Showing the first eight; more decompositions exist.
