Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69666, here are decompositions:
- 5 + 69661 = 69666
- 13 + 69653 = 69666
- 43 + 69623 = 69666
- 73 + 69593 = 69666
- 109 + 69557 = 69666
- 127 + 69539 = 69666
- 167 + 69499 = 69666
- 173 + 69493 = 69666
Showing the first eight; more decompositions exist.
