Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77980, here are decompositions:
- 3 + 77977 = 77980
- 11 + 77969 = 77980
- 29 + 77951 = 77980
- 47 + 77933 = 77980
- 113 + 77867 = 77980
- 131 + 77849 = 77980
- 167 + 77813 = 77980
- 179 + 77801 = 77980
Showing the first eight; more decompositions exist.
