Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23578, here are decompositions:
- 11 + 23567 = 23578
- 17 + 23561 = 23578
- 29 + 23549 = 23578
- 41 + 23537 = 23578
- 47 + 23531 = 23578
- 131 + 23447 = 23578
- 179 + 23399 = 23578
- 239 + 23339 = 23578
Showing the first eight; more decompositions exist.
