Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55166, here are decompositions:
- 3 + 55163 = 55166
- 19 + 55147 = 55166
- 109 + 55057 = 55166
- 157 + 55009 = 55166
- 193 + 54973 = 55166
- 337 + 54829 = 55166
- 367 + 54799 = 55166
- 379 + 54787 = 55166
Showing the first eight; more decompositions exist.
