Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4422, here are decompositions:
- 13 + 4409 = 4422
- 31 + 4391 = 4422
- 59 + 4363 = 4422
- 73 + 4349 = 4422
- 83 + 4339 = 4422
- 139 + 4283 = 4422
- 149 + 4273 = 4422
- 151 + 4271 = 4422
Showing the first eight; more decompositions exist.
