Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17772, here are decompositions:
- 11 + 17761 = 17772
- 23 + 17749 = 17772
- 43 + 17729 = 17772
- 59 + 17713 = 17772
- 89 + 17683 = 17772
- 103 + 17669 = 17772
- 113 + 17659 = 17772
- 149 + 17623 = 17772
Showing the first eight; more decompositions exist.
