Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77778, here are decompositions:
- 5 + 77773 = 77778
- 17 + 77761 = 77778
- 31 + 77747 = 77778
- 47 + 77731 = 77778
- 59 + 77719 = 77778
- 67 + 77711 = 77778
- 79 + 77699 = 77778
- 89 + 77689 = 77778
Showing the first eight; more decompositions exist.
