Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177210, here are decompositions:
- 37 + 177173 = 177210
- 43 + 177167 = 177210
- 79 + 177131 = 177210
- 83 + 177127 = 177210
- 97 + 177113 = 177210
- 101 + 177109 = 177210
- 109 + 177101 = 177210
- 167 + 177043 = 177210
Showing the first eight; more decompositions exist.
