Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18662, here are decompositions:
- 79 + 18583 = 18662
- 109 + 18553 = 18662
- 139 + 18523 = 18662
- 181 + 18481 = 18662
- 211 + 18451 = 18662
- 223 + 18439 = 18662
- 229 + 18433 = 18662
- 283 + 18379 = 18662
Showing the first eight; more decompositions exist.
