Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55172, here are decompositions:
- 151 + 55021 = 55172
- 163 + 55009 = 55172
- 193 + 54979 = 55172
- 199 + 54973 = 55172
- 223 + 54949 = 55172
- 373 + 54799 = 55172
- 421 + 54751 = 55172
- 463 + 54709 = 55172
Showing the first eight; more decompositions exist.
