Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78726, here are decompositions:
- 5 + 78721 = 78726
- 13 + 78713 = 78726
- 19 + 78707 = 78726
- 29 + 78697 = 78726
- 73 + 78653 = 78726
- 83 + 78643 = 78726
- 103 + 78623 = 78726
- 149 + 78577 = 78726
Showing the first eight; more decompositions exist.
