Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15750, here are decompositions:
- 11 + 15739 = 15750
- 13 + 15737 = 15750
- 17 + 15733 = 15750
- 19 + 15731 = 15750
- 23 + 15727 = 15750
- 67 + 15683 = 15750
- 71 + 15679 = 15750
- 79 + 15671 = 15750
Showing the first eight; more decompositions exist.
