Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76686, here are decompositions:
- 7 + 76679 = 76686
- 13 + 76673 = 76686
- 19 + 76667 = 76686
- 37 + 76649 = 76686
- 79 + 76607 = 76686
- 83 + 76603 = 76686
- 89 + 76597 = 76686
- 107 + 76579 = 76686
Showing the first eight; more decompositions exist.
