Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23172, here are decompositions:
- 5 + 23167 = 23172
- 13 + 23159 = 23172
- 29 + 23143 = 23172
- 41 + 23131 = 23172
- 73 + 23099 = 23172
- 101 + 23071 = 23172
- 109 + 23063 = 23172
- 113 + 23059 = 23172
Showing the first eight; more decompositions exist.
