Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72668, here are decompositions:
- 7 + 72661 = 72668
- 19 + 72649 = 72668
- 109 + 72559 = 72668
- 199 + 72469 = 72668
- 331 + 72337 = 72668
- 397 + 72271 = 72668
- 439 + 72229 = 72668
- 457 + 72211 = 72668
Showing the first eight; more decompositions exist.
