Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65556, here are decompositions:
- 5 + 65551 = 65556
- 13 + 65543 = 65556
- 17 + 65539 = 65556
- 19 + 65537 = 65556
- 37 + 65519 = 65556
- 59 + 65497 = 65556
- 107 + 65449 = 65556
- 109 + 65447 = 65556
Showing the first eight; more decompositions exist.
