Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77998, here are decompositions:
- 29 + 77969 = 77998
- 47 + 77951 = 77998
- 131 + 77867 = 77998
- 149 + 77849 = 77998
- 197 + 77801 = 77998
- 251 + 77747 = 77998
- 311 + 77687 = 77998
- 317 + 77681 = 77998
Showing the first eight; more decompositions exist.
