Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2194, here are decompositions:
- 41 + 2153 = 2194
- 53 + 2141 = 2194
- 83 + 2111 = 2194
- 107 + 2087 = 2194
- 113 + 2081 = 2194
- 131 + 2063 = 2194
- 167 + 2027 = 2194
- 191 + 2003 = 2194
Showing the first eight; more decompositions exist.
