Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77722, here are decompositions:
- 3 + 77719 = 77722
- 11 + 77711 = 77722
- 23 + 77699 = 77722
- 41 + 77681 = 77722
- 101 + 77621 = 77722
- 131 + 77591 = 77722
- 149 + 77573 = 77722
- 173 + 77549 = 77722
Showing the first eight; more decompositions exist.
