Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177072, here are decompositions:
- 29 + 177043 = 177072
- 53 + 177019 = 177072
- 59 + 177013 = 177072
- 61 + 177011 = 177072
- 83 + 176989 = 177072
- 89 + 176983 = 177072
- 139 + 176933 = 177072
- 149 + 176923 = 177072
Showing the first eight; more decompositions exist.
