Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55206, here are decompositions:
- 5 + 55201 = 55206
- 43 + 55163 = 55206
- 59 + 55147 = 55206
- 79 + 55127 = 55206
- 89 + 55117 = 55206
- 97 + 55109 = 55206
- 103 + 55103 = 55206
- 127 + 55079 = 55206
Showing the first eight; more decompositions exist.
