Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86920, here are decompositions:
- 59 + 86861 = 86920
- 83 + 86837 = 86920
- 107 + 86813 = 86920
- 137 + 86783 = 86920
- 149 + 86771 = 86920
- 167 + 86753 = 86920
- 191 + 86729 = 86920
- 227 + 86693 = 86920
Showing the first eight; more decompositions exist.
