Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55972, here are decompositions:
- 5 + 55967 = 55972
- 23 + 55949 = 55972
- 41 + 55931 = 55972
- 71 + 55901 = 55972
- 83 + 55889 = 55972
- 101 + 55871 = 55972
- 149 + 55823 = 55972
- 173 + 55799 = 55972
Showing the first eight; more decompositions exist.
