Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15760, here are decompositions:
- 11 + 15749 = 15760
- 23 + 15737 = 15760
- 29 + 15731 = 15760
- 89 + 15671 = 15760
- 113 + 15647 = 15760
- 131 + 15629 = 15760
- 179 + 15581 = 15760
- 191 + 15569 = 15760
Showing the first eight; more decompositions exist.
