Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76728, here are decompositions:
- 11 + 76717 = 76728
- 31 + 76697 = 76728
- 61 + 76667 = 76728
- 79 + 76649 = 76728
- 97 + 76631 = 76728
- 131 + 76597 = 76728
- 149 + 76579 = 76728
- 167 + 76561 = 76728
Showing the first eight; more decompositions exist.
