Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55120, here are decompositions:
- 3 + 55117 = 55120
- 11 + 55109 = 55120
- 17 + 55103 = 55120
- 41 + 55079 = 55120
- 47 + 55073 = 55120
- 59 + 55061 = 55120
- 71 + 55049 = 55120
- 137 + 54983 = 55120
Showing the first eight; more decompositions exist.
