Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51740, here are decompositions:
- 19 + 51721 = 51740
- 61 + 51679 = 51740
- 67 + 51673 = 51740
- 103 + 51637 = 51740
- 109 + 51631 = 51740
- 127 + 51613 = 51740
- 163 + 51577 = 51740
- 223 + 51517 = 51740
Showing the first eight; more decompositions exist.
