Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55100, here are decompositions:
- 43 + 55057 = 55100
- 79 + 55021 = 55100
- 127 + 54973 = 55100
- 151 + 54949 = 55100
- 181 + 54919 = 55100
- 193 + 54907 = 55100
- 223 + 54877 = 55100
- 271 + 54829 = 55100
Showing the first eight; more decompositions exist.
