Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19124, here are decompositions:
- 3 + 19121 = 19124
- 37 + 19087 = 19124
- 43 + 19081 = 19124
- 73 + 19051 = 19124
- 151 + 18973 = 19124
- 211 + 18913 = 19124
- 331 + 18793 = 19124
- 337 + 18787 = 19124
Showing the first eight; more decompositions exist.
