Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71986, here are decompositions:
- 3 + 71983 = 71986
- 23 + 71963 = 71986
- 53 + 71933 = 71986
- 107 + 71879 = 71986
- 137 + 71849 = 71986
- 149 + 71837 = 71986
- 179 + 71807 = 71986
- 197 + 71789 = 71986
Showing the first eight; more decompositions exist.
