Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166286, here are decompositions:
- 13 + 166273 = 166286
- 67 + 166219 = 166286
- 79 + 166207 = 166286
- 97 + 166189 = 166286
- 103 + 166183 = 166286
- 139 + 166147 = 166286
- 223 + 166063 = 166286
- 409 + 165877 = 166286
Showing the first eight; more decompositions exist.
