Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177192, here are decompositions:
- 19 + 177173 = 177192
- 61 + 177131 = 177192
- 79 + 177113 = 177192
- 83 + 177109 = 177192
- 101 + 177091 = 177192
- 149 + 177043 = 177192
- 173 + 177019 = 177192
- 179 + 177013 = 177192
Showing the first eight; more decompositions exist.
