Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77838, here are decompositions:
- 37 + 77801 = 77838
- 41 + 77797 = 77838
- 107 + 77731 = 77838
- 127 + 77711 = 77838
- 139 + 77699 = 77838
- 149 + 77689 = 77838
- 151 + 77687 = 77838
- 157 + 77681 = 77838
Showing the first eight; more decompositions exist.
