Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77772, here are decompositions:
- 11 + 77761 = 77772
- 29 + 77743 = 77772
- 41 + 77731 = 77772
- 53 + 77719 = 77772
- 59 + 77713 = 77772
- 61 + 77711 = 77772
- 73 + 77699 = 77772
- 83 + 77689 = 77772
Showing the first eight; more decompositions exist.
