Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51700, here are decompositions:
- 17 + 51683 = 51700
- 41 + 51659 = 51700
- 53 + 51647 = 51700
- 101 + 51599 = 51700
- 107 + 51593 = 51700
- 137 + 51563 = 51700
- 149 + 51551 = 51700
- 179 + 51521 = 51700
Showing the first eight; more decompositions exist.
