Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23436, here are decompositions:
- 5 + 23431 = 23436
- 19 + 23417 = 23436
- 37 + 23399 = 23436
- 67 + 23369 = 23436
- 79 + 23357 = 23436
- 97 + 23339 = 23436
- 103 + 23333 = 23436
- 109 + 23327 = 23436
Showing the first eight; more decompositions exist.
