Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51784, here are decompositions:
- 17 + 51767 = 51784
- 71 + 51713 = 51784
- 101 + 51683 = 51784
- 137 + 51647 = 51784
- 191 + 51593 = 51784
- 233 + 51551 = 51784
- 263 + 51521 = 51784
- 281 + 51503 = 51784
Showing the first eight; more decompositions exist.
