Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118128, here are decompositions:
- 47 + 118081 = 118128
- 67 + 118061 = 118128
- 71 + 118057 = 118128
- 137 + 117991 = 118128
- 139 + 117989 = 118128
- 149 + 117979 = 118128
- 151 + 117977 = 118128
- 191 + 117937 = 118128
Showing the first eight; more decompositions exist.
