Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17172, here are decompositions:
- 5 + 17167 = 17172
- 13 + 17159 = 17172
- 73 + 17099 = 17172
- 79 + 17093 = 17172
- 131 + 17041 = 17172
- 139 + 17033 = 17172
- 151 + 17021 = 17172
- 179 + 16993 = 17172
Showing the first eight; more decompositions exist.
