Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177140, here are decompositions:
- 13 + 177127 = 177140
- 31 + 177109 = 177140
- 97 + 177043 = 177140
- 127 + 177013 = 177140
- 151 + 176989 = 177140
- 157 + 176983 = 177140
- 163 + 176977 = 177140
- 241 + 176899 = 177140
Showing the first eight; more decompositions exist.
