Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177372, here are decompositions:
- 53 + 177319 = 177372
- 71 + 177301 = 177372
- 89 + 177283 = 177372
- 103 + 177269 = 177372
- 149 + 177223 = 177372
- 163 + 177209 = 177372
- 199 + 177173 = 177372
- 241 + 177131 = 177372
Showing the first eight; more decompositions exist.
