Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15768, here are decompositions:
- 7 + 15761 = 15768
- 19 + 15749 = 15768
- 29 + 15739 = 15768
- 31 + 15737 = 15768
- 37 + 15731 = 15768
- 41 + 15727 = 15768
- 89 + 15679 = 15768
- 97 + 15671 = 15768
Showing the first eight; more decompositions exist.
