Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19194, here are decompositions:
- 11 + 19183 = 19194
- 13 + 19181 = 19194
- 31 + 19163 = 19194
- 37 + 19157 = 19194
- 53 + 19141 = 19194
- 73 + 19121 = 19194
- 107 + 19087 = 19194
- 113 + 19081 = 19194
Showing the first eight; more decompositions exist.
