Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23572, here are decompositions:
- 5 + 23567 = 23572
- 11 + 23561 = 23572
- 23 + 23549 = 23572
- 41 + 23531 = 23572
- 113 + 23459 = 23572
- 173 + 23399 = 23572
- 233 + 23339 = 23572
- 239 + 23333 = 23572
Showing the first eight; more decompositions exist.
