Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177218, here are decompositions:
- 7 + 177211 = 177218
- 109 + 177109 = 177218
- 127 + 177091 = 177218
- 199 + 177019 = 177218
- 211 + 177007 = 177218
- 229 + 176989 = 177218
- 241 + 176977 = 177218
- 331 + 176887 = 177218
Showing the first eight; more decompositions exist.
