Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15662, here are decompositions:
- 13 + 15649 = 15662
- 19 + 15643 = 15662
- 43 + 15619 = 15662
- 61 + 15601 = 15662
- 79 + 15583 = 15662
- 103 + 15559 = 15662
- 151 + 15511 = 15662
- 211 + 15451 = 15662
Showing the first eight; more decompositions exist.
