Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166670, here are decompositions:
- 3 + 166667 = 166670
- 13 + 166657 = 166670
- 43 + 166627 = 166670
- 61 + 166609 = 166670
- 67 + 166603 = 166670
- 73 + 166597 = 166670
- 103 + 166567 = 166670
- 109 + 166561 = 166670
Showing the first eight; more decompositions exist.
