Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77854, here are decompositions:
- 5 + 77849 = 77854
- 41 + 77813 = 77854
- 53 + 77801 = 77854
- 71 + 77783 = 77854
- 107 + 77747 = 77854
- 131 + 77723 = 77854
- 167 + 77687 = 77854
- 173 + 77681 = 77854
Showing the first eight; more decompositions exist.
