Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177180, here are decompositions:
- 7 + 177173 = 177180
- 13 + 177167 = 177180
- 53 + 177127 = 177180
- 67 + 177113 = 177180
- 71 + 177109 = 177180
- 79 + 177101 = 177180
- 89 + 177091 = 177180
- 137 + 177043 = 177180
Showing the first eight; more decompositions exist.
