Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8118, here are decompositions:
- 7 + 8111 = 8118
- 17 + 8101 = 8118
- 29 + 8089 = 8118
- 31 + 8087 = 8118
- 37 + 8081 = 8118
- 59 + 8059 = 8118
- 79 + 8039 = 8118
- 101 + 8017 = 8118
Showing the first eight; more decompositions exist.
