Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18332, here are decompositions:
- 3 + 18329 = 18332
- 19 + 18313 = 18332
- 31 + 18301 = 18332
- 43 + 18289 = 18332
- 79 + 18253 = 18332
- 103 + 18229 = 18332
- 109 + 18223 = 18332
- 151 + 18181 = 18332
Showing the first eight; more decompositions exist.
