Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77928, here are decompositions:
- 29 + 77899 = 77928
- 61 + 77867 = 77928
- 79 + 77849 = 77928
- 89 + 77839 = 77928
- 127 + 77801 = 77928
- 131 + 77797 = 77928
- 167 + 77761 = 77928
- 181 + 77747 = 77928
Showing the first eight; more decompositions exist.
