Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15928, here are decompositions:
- 5 + 15923 = 15928
- 41 + 15887 = 15928
- 47 + 15881 = 15928
- 131 + 15797 = 15928
- 137 + 15791 = 15928
- 167 + 15761 = 15928
- 179 + 15749 = 15928
- 191 + 15737 = 15928
Showing the first eight; more decompositions exist.
