Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77844, here are decompositions:
- 5 + 77839 = 77844
- 31 + 77813 = 77844
- 43 + 77801 = 77844
- 47 + 77797 = 77844
- 61 + 77783 = 77844
- 71 + 77773 = 77844
- 83 + 77761 = 77844
- 97 + 77747 = 77844
Showing the first eight; more decompositions exist.
