Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19104, here are decompositions:
- 17 + 19087 = 19104
- 23 + 19081 = 19104
- 31 + 19073 = 19104
- 53 + 19051 = 19104
- 67 + 19037 = 19104
- 73 + 19031 = 19104
- 103 + 19001 = 19104
- 131 + 18973 = 19104
Showing the first eight; more decompositions exist.
