Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1954, here are decompositions:
- 3 + 1951 = 1954
- 5 + 1949 = 1954
- 23 + 1931 = 1954
- 41 + 1913 = 1954
- 47 + 1907 = 1954
- 53 + 1901 = 1954
- 83 + 1871 = 1954
- 107 + 1847 = 1954
Showing the first eight; more decompositions exist.
