Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51698, here are decompositions:
- 7 + 51691 = 51698
- 19 + 51679 = 51698
- 61 + 51637 = 51698
- 67 + 51631 = 51698
- 181 + 51517 = 51698
- 211 + 51487 = 51698
- 271 + 51427 = 51698
- 277 + 51421 = 51698
Showing the first eight; more decompositions exist.
