Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2126, here are decompositions:
- 13 + 2113 = 2126
- 37 + 2089 = 2126
- 43 + 2083 = 2126
- 73 + 2053 = 2126
- 97 + 2029 = 2126
- 109 + 2017 = 2126
- 127 + 1999 = 2126
- 139 + 1987 = 2126
Showing the first eight; more decompositions exist.
