Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4222, here are decompositions:
- 3 + 4219 = 4222
- 5 + 4217 = 4222
- 11 + 4211 = 4222
- 83 + 4139 = 4222
- 89 + 4133 = 4222
- 131 + 4091 = 4222
- 149 + 4073 = 4222
- 173 + 4049 = 4222
Showing the first eight; more decompositions exist.
