Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42668, here are decompositions:
- 19 + 42649 = 42668
- 79 + 42589 = 42668
- 97 + 42571 = 42668
- 181 + 42487 = 42668
- 211 + 42457 = 42668
- 271 + 42397 = 42668
- 277 + 42391 = 42668
- 331 + 42337 = 42668
Showing the first eight; more decompositions exist.
