Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55312, here are decompositions:
- 53 + 55259 = 55312
- 83 + 55229 = 55312
- 149 + 55163 = 55312
- 233 + 55079 = 55312
- 239 + 55073 = 55312
- 251 + 55061 = 55312
- 263 + 55049 = 55312
- 311 + 55001 = 55312
Showing the first eight; more decompositions exist.
