Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4170, here are decompositions:
- 11 + 4159 = 4170
- 13 + 4157 = 4170
- 17 + 4153 = 4170
- 31 + 4139 = 4170
- 37 + 4133 = 4170
- 41 + 4129 = 4170
- 43 + 4127 = 4170
- 59 + 4111 = 4170
Showing the first eight; more decompositions exist.
