Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18552, here are decompositions:
- 11 + 18541 = 18552
- 13 + 18539 = 18552
- 29 + 18523 = 18552
- 31 + 18521 = 18552
- 59 + 18493 = 18552
- 71 + 18481 = 18552
- 101 + 18451 = 18552
- 109 + 18443 = 18552
Showing the first eight; more decompositions exist.
