Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5172, here are decompositions:
- 5 + 5167 = 5172
- 19 + 5153 = 5172
- 53 + 5119 = 5172
- 59 + 5113 = 5172
- 71 + 5101 = 5172
- 73 + 5099 = 5172
- 113 + 5059 = 5172
- 149 + 5023 = 5172
Showing the first eight; more decompositions exist.
