Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75172, here are decompositions:
- 3 + 75169 = 75172
- 5 + 75167 = 75172
- 11 + 75161 = 75172
- 23 + 75149 = 75172
- 89 + 75083 = 75172
- 131 + 75041 = 75172
- 239 + 74933 = 75172
- 269 + 74903 = 75172
Showing the first eight; more decompositions exist.
