Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55200, here are decompositions:
- 29 + 55171 = 55200
- 37 + 55163 = 55200
- 53 + 55147 = 55200
- 73 + 55127 = 55200
- 83 + 55117 = 55200
- 97 + 55103 = 55200
- 127 + 55073 = 55200
- 139 + 55061 = 55200
Showing the first eight; more decompositions exist.
