Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177310, here are decompositions:
- 41 + 177269 = 177310
- 53 + 177257 = 177310
- 71 + 177239 = 177310
- 101 + 177209 = 177310
- 137 + 177173 = 177310
- 179 + 177131 = 177310
- 197 + 177113 = 177310
- 359 + 176951 = 177310
Showing the first eight; more decompositions exist.
