Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16220, here are decompositions:
- 3 + 16217 = 16220
- 31 + 16189 = 16220
- 37 + 16183 = 16220
- 79 + 16141 = 16220
- 109 + 16111 = 16220
- 151 + 16069 = 16220
- 157 + 16063 = 16220
- 163 + 16057 = 16220
Showing the first eight; more decompositions exist.
