Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28484, here are decompositions:
- 7 + 28477 = 28484
- 37 + 28447 = 28484
- 73 + 28411 = 28484
- 97 + 28387 = 28484
- 283 + 28201 = 28484
- 373 + 28111 = 28484
- 397 + 28087 = 28484
- 433 + 28051 = 28484
Showing the first eight; more decompositions exist.
