Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55986, here are decompositions:
- 19 + 55967 = 55986
- 37 + 55949 = 55986
- 53 + 55933 = 55986
- 59 + 55927 = 55986
- 83 + 55903 = 55986
- 89 + 55897 = 55986
- 97 + 55889 = 55986
- 137 + 55849 = 55986
Showing the first eight; more decompositions exist.
