Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87106, here are decompositions:
- 3 + 87103 = 87106
- 23 + 87083 = 87106
- 113 + 86993 = 87106
- 137 + 86969 = 87106
- 167 + 86939 = 87106
- 179 + 86927 = 87106
- 263 + 86843 = 87106
- 269 + 86837 = 87106
Showing the first eight; more decompositions exist.
