Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1946, here are decompositions:
- 13 + 1933 = 1946
- 67 + 1879 = 1946
- 73 + 1873 = 1946
- 79 + 1867 = 1946
- 157 + 1789 = 1946
- 163 + 1783 = 1946
- 193 + 1753 = 1946
- 199 + 1747 = 1946
Showing the first eight; more decompositions exist.
