Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5112, here are decompositions:
- 5 + 5107 = 5112
- 11 + 5101 = 5112
- 13 + 5099 = 5112
- 31 + 5081 = 5112
- 53 + 5059 = 5112
- 61 + 5051 = 5112
- 73 + 5039 = 5112
- 89 + 5023 = 5112
Showing the first eight; more decompositions exist.
