Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118290, here are decompositions:
- 13 + 118277 = 118290
- 17 + 118273 = 118290
- 31 + 118259 = 118290
- 37 + 118253 = 118290
- 41 + 118249 = 118290
- 43 + 118247 = 118290
- 71 + 118219 = 118290
- 79 + 118211 = 118290
Showing the first eight; more decompositions exist.
