Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23442, here are decompositions:
- 11 + 23431 = 23442
- 43 + 23399 = 23442
- 71 + 23371 = 23442
- 73 + 23369 = 23442
- 103 + 23339 = 23442
- 109 + 23333 = 23442
- 131 + 23311 = 23442
- 149 + 23293 = 23442
Showing the first eight; more decompositions exist.
