Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4172, here are decompositions:
- 13 + 4159 = 4172
- 19 + 4153 = 4172
- 43 + 4129 = 4172
- 61 + 4111 = 4172
- 73 + 4099 = 4172
- 79 + 4093 = 4172
- 151 + 4021 = 4172
- 229 + 3943 = 4172
Showing the first eight; more decompositions exist.
