Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55208, here are decompositions:
- 7 + 55201 = 55208
- 37 + 55171 = 55208
- 61 + 55147 = 55208
- 151 + 55057 = 55208
- 157 + 55051 = 55208
- 199 + 55009 = 55208
- 229 + 54979 = 55208
- 331 + 54877 = 55208
Showing the first eight; more decompositions exist.
