Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77898, here are decompositions:
- 5 + 77893 = 77898
- 31 + 77867 = 77898
- 59 + 77839 = 77898
- 97 + 77801 = 77898
- 101 + 77797 = 77898
- 137 + 77761 = 77898
- 151 + 77747 = 77898
- 167 + 77731 = 77898
Showing the first eight; more decompositions exist.
