Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77566, here are decompositions:
- 3 + 77563 = 77566
- 17 + 77549 = 77566
- 23 + 77543 = 77566
- 53 + 77513 = 77566
- 89 + 77477 = 77566
- 149 + 77417 = 77566
- 197 + 77369 = 77566
- 227 + 77339 = 77566
Showing the first eight; more decompositions exist.
