Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19188, here are decompositions:
- 5 + 19183 = 19188
- 7 + 19181 = 19188
- 31 + 19157 = 19188
- 47 + 19141 = 19188
- 67 + 19121 = 19188
- 101 + 19087 = 19188
- 107 + 19081 = 19188
- 109 + 19079 = 19188
Showing the first eight; more decompositions exist.
