Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55216, here are decompositions:
- 3 + 55213 = 55216
- 53 + 55163 = 55216
- 89 + 55127 = 55216
- 107 + 55109 = 55216
- 113 + 55103 = 55216
- 137 + 55079 = 55216
- 167 + 55049 = 55216
- 233 + 54983 = 55216
Showing the first eight; more decompositions exist.
