Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177230, here are decompositions:
- 7 + 177223 = 177230
- 13 + 177217 = 177230
- 19 + 177211 = 177230
- 103 + 177127 = 177230
- 139 + 177091 = 177230
- 211 + 177019 = 177230
- 223 + 177007 = 177230
- 241 + 176989 = 177230
Showing the first eight; more decompositions exist.
