Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43172, here are decompositions:
- 13 + 43159 = 43172
- 79 + 43093 = 43172
- 109 + 43063 = 43172
- 193 + 42979 = 43172
- 211 + 42961 = 43172
- 229 + 42943 = 43172
- 271 + 42901 = 43172
- 313 + 42859 = 43172
Showing the first eight; more decompositions exist.
