Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2078, here are decompositions:
- 61 + 2017 = 2078
- 67 + 2011 = 2078
- 79 + 1999 = 2078
- 127 + 1951 = 2078
- 199 + 1879 = 2078
- 211 + 1867 = 2078
- 277 + 1801 = 2078
- 331 + 1747 = 2078
Showing the first eight; more decompositions exist.
