Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118388, here are decompositions:
- 19 + 118369 = 118388
- 139 + 118249 = 118388
- 199 + 118189 = 118388
- 241 + 118147 = 118388
- 307 + 118081 = 118388
- 331 + 118057 = 118388
- 337 + 118051 = 118388
- 397 + 117991 = 118388
Showing the first eight; more decompositions exist.
