Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76870, here are decompositions:
- 23 + 76847 = 76870
- 41 + 76829 = 76870
- 89 + 76781 = 76870
- 113 + 76757 = 76870
- 137 + 76733 = 76870
- 173 + 76697 = 76870
- 191 + 76679 = 76870
- 197 + 76673 = 76870
Showing the first eight; more decompositions exist.
