Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2026, here are decompositions:
- 23 + 2003 = 2026
- 29 + 1997 = 2026
- 47 + 1979 = 2026
- 53 + 1973 = 2026
- 113 + 1913 = 2026
- 137 + 1889 = 2026
- 149 + 1877 = 2026
- 179 + 1847 = 2026
Showing the first eight; more decompositions exist.
