Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52720, here are decompositions:
- 11 + 52709 = 52720
- 23 + 52697 = 52720
- 29 + 52691 = 52720
- 47 + 52673 = 52720
- 53 + 52667 = 52720
- 89 + 52631 = 52720
- 137 + 52583 = 52720
- 149 + 52571 = 52720
Showing the first eight; more decompositions exist.
