Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15968, here are decompositions:
- 31 + 15937 = 15968
- 61 + 15907 = 15968
- 67 + 15901 = 15968
- 79 + 15889 = 15968
- 109 + 15859 = 15968
- 151 + 15817 = 15968
- 181 + 15787 = 15968
- 229 + 15739 = 15968
Showing the first eight; more decompositions exist.
