Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77904, here are decompositions:
- 5 + 77899 = 77904
- 11 + 77893 = 77904
- 37 + 77867 = 77904
- 41 + 77863 = 77904
- 103 + 77801 = 77904
- 107 + 77797 = 77904
- 131 + 77773 = 77904
- 157 + 77747 = 77904
Showing the first eight; more decompositions exist.
