Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16228, here are decompositions:
- 5 + 16223 = 16228
- 11 + 16217 = 16228
- 41 + 16187 = 16228
- 89 + 16139 = 16228
- 101 + 16127 = 16228
- 131 + 16097 = 16228
- 137 + 16091 = 16228
- 167 + 16061 = 16228
Showing the first eight; more decompositions exist.
