Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4228, here are decompositions:
- 11 + 4217 = 4228
- 17 + 4211 = 4228
- 71 + 4157 = 4228
- 89 + 4139 = 4228
- 101 + 4127 = 4228
- 137 + 4091 = 4228
- 149 + 4079 = 4228
- 179 + 4049 = 4228
Showing the first eight; more decompositions exist.
