Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170166, here are decompositions:
- 43 + 170123 = 170166
- 67 + 170099 = 170166
- 103 + 170063 = 170166
- 109 + 170057 = 170166
- 137 + 170029 = 170166
- 163 + 170003 = 170166
- 179 + 169987 = 170166
- 223 + 169943 = 170166
Showing the first eight; more decompositions exist.
