Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16118, here are decompositions:
- 7 + 16111 = 16118
- 31 + 16087 = 16118
- 61 + 16057 = 16118
- 127 + 15991 = 16118
- 181 + 15937 = 16118
- 199 + 15919 = 16118
- 211 + 15907 = 16118
- 229 + 15889 = 16118
Showing the first eight; more decompositions exist.
