Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78930, here are decompositions:
- 11 + 78919 = 78930
- 29 + 78901 = 78930
- 37 + 78893 = 78930
- 41 + 78889 = 78930
- 43 + 78887 = 78930
- 53 + 78877 = 78930
- 73 + 78857 = 78930
- 107 + 78823 = 78930
Showing the first eight; more decompositions exist.
