Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51782, here are decompositions:
- 13 + 51769 = 51782
- 61 + 51721 = 51782
- 103 + 51679 = 51782
- 109 + 51673 = 51782
- 151 + 51631 = 51782
- 271 + 51511 = 51782
- 421 + 51361 = 51782
- 433 + 51349 = 51782
Showing the first eight; more decompositions exist.
