Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7772, here are decompositions:
- 13 + 7759 = 7772
- 19 + 7753 = 7772
- 31 + 7741 = 7772
- 73 + 7699 = 7772
- 103 + 7669 = 7772
- 151 + 7621 = 7772
- 181 + 7591 = 7772
- 199 + 7573 = 7772
Showing the first eight; more decompositions exist.
