Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177184, here are decompositions:
- 11 + 177173 = 177184
- 17 + 177167 = 177184
- 53 + 177131 = 177184
- 71 + 177113 = 177184
- 83 + 177101 = 177184
- 173 + 177011 = 177184
- 233 + 176951 = 177184
- 251 + 176933 = 177184
Showing the first eight; more decompositions exist.
