Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177202, here are decompositions:
- 29 + 177173 = 177202
- 71 + 177131 = 177202
- 89 + 177113 = 177202
- 101 + 177101 = 177202
- 191 + 177011 = 177202
- 251 + 176951 = 177202
- 269 + 176933 = 177202
- 281 + 176921 = 177202
Showing the first eight; more decompositions exist.
