Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87028, here are decompositions:
- 17 + 87011 = 87028
- 47 + 86981 = 87028
- 59 + 86969 = 87028
- 89 + 86939 = 87028
- 101 + 86927 = 87028
- 167 + 86861 = 87028
- 191 + 86837 = 87028
- 257 + 86771 = 87028
Showing the first eight; more decompositions exist.
