Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18632, here are decompositions:
- 79 + 18553 = 18632
- 109 + 18523 = 18632
- 139 + 18493 = 18632
- 151 + 18481 = 18632
- 181 + 18451 = 18632
- 193 + 18439 = 18632
- 199 + 18433 = 18632
- 331 + 18301 = 18632
Showing the first eight; more decompositions exist.
