Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118090, here are decompositions:
- 29 + 118061 = 118090
- 47 + 118043 = 118090
- 53 + 118037 = 118090
- 101 + 117989 = 118090
- 113 + 117977 = 118090
- 131 + 117959 = 118090
- 173 + 117917 = 118090
- 179 + 117911 = 118090
Showing the first eight; more decompositions exist.
