Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1994, here are decompositions:
- 7 + 1987 = 1994
- 43 + 1951 = 1994
- 61 + 1933 = 1994
- 127 + 1867 = 1994
- 163 + 1831 = 1994
- 193 + 1801 = 1994
- 211 + 1783 = 1994
- 241 + 1753 = 1994
Showing the first eight; more decompositions exist.
