Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87112, here are decompositions:
- 5 + 87107 = 87112
- 29 + 87083 = 87112
- 41 + 87071 = 87112
- 71 + 87041 = 87112
- 101 + 87011 = 87112
- 131 + 86981 = 87112
- 173 + 86939 = 87112
- 251 + 86861 = 87112
Showing the first eight; more decompositions exist.
