Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4208, here are decompositions:
- 7 + 4201 = 4208
- 31 + 4177 = 4208
- 79 + 4129 = 4208
- 97 + 4111 = 4208
- 109 + 4099 = 4208
- 151 + 4057 = 4208
- 157 + 4051 = 4208
- 181 + 4027 = 4208
Showing the first eight; more decompositions exist.
