Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15112, here are decompositions:
- 5 + 15107 = 15112
- 11 + 15101 = 15112
- 29 + 15083 = 15112
- 59 + 15053 = 15112
- 173 + 14939 = 15112
- 233 + 14879 = 15112
- 269 + 14843 = 15112
- 281 + 14831 = 15112
Showing the first eight; more decompositions exist.
