Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23400, here are decompositions:
- 29 + 23371 = 23400
- 31 + 23369 = 23400
- 43 + 23357 = 23400
- 61 + 23339 = 23400
- 67 + 23333 = 23400
- 73 + 23327 = 23400
- 79 + 23321 = 23400
- 89 + 23311 = 23400
Showing the first eight; more decompositions exist.
