Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51528, here are decompositions:
- 7 + 51521 = 51528
- 11 + 51517 = 51528
- 17 + 51511 = 51528
- 41 + 51487 = 51528
- 47 + 51481 = 51528
- 67 + 51461 = 51528
- 79 + 51449 = 51528
- 89 + 51439 = 51528
Showing the first eight; more decompositions exist.
