Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177272, here are decompositions:
- 3 + 177269 = 177272
- 61 + 177211 = 177272
- 163 + 177109 = 177272
- 181 + 177091 = 177272
- 229 + 177043 = 177272
- 283 + 176989 = 177272
- 349 + 176923 = 177272
- 373 + 176899 = 177272
Showing the first eight; more decompositions exist.
