Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51730, here are decompositions:
- 11 + 51719 = 51730
- 17 + 51713 = 51730
- 47 + 51683 = 51730
- 71 + 51659 = 51730
- 83 + 51647 = 51730
- 131 + 51599 = 51730
- 137 + 51593 = 51730
- 149 + 51581 = 51730
Showing the first eight; more decompositions exist.
