Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87910, here are decompositions:
- 23 + 87887 = 87910
- 29 + 87881 = 87910
- 41 + 87869 = 87910
- 107 + 87803 = 87910
- 113 + 87797 = 87910
- 167 + 87743 = 87910
- 191 + 87719 = 87910
- 227 + 87683 = 87910
Showing the first eight; more decompositions exist.
