Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15772, here are decompositions:
- 5 + 15767 = 15772
- 11 + 15761 = 15772
- 23 + 15749 = 15772
- 41 + 15731 = 15772
- 89 + 15683 = 15772
- 101 + 15671 = 15772
- 131 + 15641 = 15772
- 191 + 15581 = 15772
Showing the first eight; more decompositions exist.
